  "abstract": "An anti-vibration fastening member may include a first fastening portion formed of an elastic material and comprising a shaft coupled to a shaft coupling hole provided at an actuator, and a second fastening portion integrated with the first fastening portion and comprising holding protrusions introduced into a mounting groove provided at a counterpart on which the actuator is mounted and then held by rotation.",
  "claims": [
    "1. An anti-vibration fastening member comprising: a first fastening portion formed of an elastic material and comprising a shaft coupled to a shaft coupling hole disposed at an actuator; and a second fastening portion integrated with the first fastening portion and comprising holding protrusions introduced into a mounting groove disposed at a counterpart on which the actuator is mounted and then held by rotation, wherein the first fastening portion further comprises a spiral protrusion formed on an outer surface of the shaft to be fastened to a spiral groove firmed on an inner surface of the shaft coupling hole.",
    "2. The anti-vibration fastening member according to claim 1, wherein the first fastening portion comprises: an entry guiding surface formed at a tip of the shaft and having a cone shape; and a dislocation prevention protrusion formed at a circumferential area of the shaft with a greater diameter than an outer diameter of the shaft and held after passing through the shaft coupling hole.",
    "3. The anti-vibration fastening member according to claim 1, wherein the second fastening portion comprises a support protrusion configured to cover the mounting groove and held by one surface of the counterpart, and a central support portion configured to pass through the mounting groove and protrude to an opposite side of the counterpart; and the holding protrusions radially extend from the central support portion and are held by an opposite surface of the counterpart by rotation.",
    "4. The anti-vibration fastening member according to claim 3, wherein at least one of the support protrusion and the holding protrusion comprises a rotation limiter having a groove or protrusion shape held by the counterpart to limit rotation after a coupling process is completed.",
    "5. A vehicle actuator fastening device comprising: a first coupling portion disposed at an actuator and having a shaft coupling hole; a second coupling portion disposed at a counterpart on which the actuator is mounted and having a mounting groove with an opening; and an anti-vibration fastening member configured to mediate coupling between the first coupling portion and the second coupling portion and formed of an elastic material, wherein the anti-vibration fastening member comprises: a first fastening portion comprising a shaft coupled to the shaft coupling hole of the first coupling portion; and a second fastening portion integrated with the first fastening portion and comprising holding protrusions introduced into the mounting groove of the second coupling portion and then held by rotation, wherein the first fastening portion comprises an entry guiding surface formed at a tip of the shaft and having a cone shape and a dislocation prevention protrusion formed at a circumferential area of the shaft with a greater diameter than an outer diameter of the shaft and held after passing through the shaft coupling hole.",
    "6. The vehicle actuator fastening device according to claim 5, wherein the first fastening portion further comprises a spiral protrusion formed on an outer surface of the shaft; and the first coupling portion further comprises a spiral groove formed on an inner surface of the shaft coupling hole to which the spiral protrusion is coupled by rotation.",
    "7. The vehicle actuator fastening device according to claim 5, wherein the mounting groove comprises a central groove portion having a circular shape and extending groove portions extending radially outward from both sides of the central groove portion for entry of the holding protrusions; the second fastening portion comprises a support protrusion having a diameter greater than that of the central groove portion to be held by one surface of the counterpart, and a central support portion passing through the central groove portion and protruding to an opposite side of the counterpart; and the holding protrusions radially extend from the central support portion at positions corresponding to the extending groove portions and held by an opposite surface of the counterpart by rotation.",
    "8. The vehicle actuator fastening device according to claim 7, wherein the extending groove portions extend in sector form at the circumference of the central groove portion; and the holding protrusions have shapes corresponding to shapes of the extending groove portions.",
    "9. The vehicle actuator fastening device according to claim 7, wherein rotation limiters with uneven surfaces are provided on a first surface of each of the support protrusion and the counterpart and engaged with each other to limit rotation of the anti-vibration fastening member after fastening the anti-vibration fastening member.",
    "10. The vehicle actuator fastening device according to claim 7, wherein rotation limiters with uneven surfaces are provided on a second surface of each of the holding protrusion and the counterpart and engaged with each other to limit rotation of the anti-vibration fastening member after fastening the anti-vibration fastening member."

  "description_excerpt": "Field of the Invention Various embodiments of the present invention relate to anti-vibration fastening members configured to stably fasten an actuator while reducing transmission of vibration of the actuator and vehicle actuator fastening devices including the same. Description of Related Art Vehicles are equipped with various types of electric actuators. The electric actuators are mounted on various portions of vehicles to automatically perform operation of locking and unlocking a door or a trunk, operation of opening and closing a sunroof, operation of lifting and lowering a window glass, and the like. For example, a power latch system installed at a door of a vehicle locks the door after completely closing the door when the door is not completely closed. The power latch system includes an actuator provided with a motor and a latch connected to the actuator via a cable and configured to lock and unlock the door in accordance with operation of the actuator. The actuator is fixed to a panel of a door module by fastening a plurality of bolts thereto.\n\nHowever, since vibration of an actuator mounted on the panel by using the bolts is transmitted to the panel of the door module, noise may be caused by vibration of the door module. The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.",
