  "claims": [
    "1. A connector provided to a connection between a vibrating body that is a vibration source, and a plate-shaped shielding body that is attached to the vibrating body, the connector comprising: a first buffer member that includes a spiral-shaped wire in a plan view; a second buffer member that is substantially annular and flat plate-shaped, that is capable of warping in a thickness direction, and that is stacked with the first buffer member; a collar member that includes a cylindrical portion having an insertion hole for a fixing member for attaching the connector to the vibrating body, the cylindrical portion surrounded by the first buffer member and the second buffer member and extending through annular apertures thereof, a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member, the first and the second flanges both protruding from the cylindrical portion in a radial direction and clamping the first and second buffer members therebetween; and a coupling member that includes a first holder section holding radially outer sides of the first buffer member and the second buffer member and clamping the first and second buffer members therein, a second holder section holding the shielding body, and a coupling member base portion connecting the first holder section and the second holder section, wherein: a gap for allowing the second buffer member to move in the radial direction is formed between the second buffer member and the cylindrical portion, and the radially inner sides of the first buffer member and the second buffer member are sandwiched by the first flange and the second flange in such a manner that the second buffer member is movable in the radial direction and limits axial deformation of the first buffer member.",
    "2. A connector according to claim 1, wherein the second buffer member is made from a substantially annular and flat metallic mesh material or spring steel material.",
    "3. A connector provided to a connection between a vibrating body that is a vibration source, and a plate-shaped shielding body that is attached to the vibrating body, the connector comprising: a first buffer member that includes a spiral-shaped wire in a plan view; a second buffer member that is substantially annular and flat plate-shaped, that is capable of warping in a thickness direction, and that is stacked with the first buffer member; a third buffer member that includes a spiral-shaped wire in a plan view, and that is stacked with the second buffer member on a side opposite to the first buffer member; a collar member that includes a cylindrical portion having an insertion hole for a fixing member for attaching the connector to the vibrating body, and the cylindrical portion surrounded by the first buffer member, the second buffer member, and the third buffer member and extending through annular apertures thereof, a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the third buffer member, the first and the second flanges both protruding in a radial direction and clamping the first, second and third buffer members therebetween; and a coupling member that includes a first holder section holding radially outer sides of the first buffer member, the second buffer member, and the third buffer member and clamping the first, second and third buffer members therein, a second holder section holding the shielding body, and a coupling member base portion connecting the first holder section and the second holder section, wherein: a gap for allowing the second buffer member to move in the radial direction is formed between the second buffer member and the cylindrical portion, and the radially inner sides of the first buffer member, the second buffer member, and the third buffer member are sandwiched by the first flange and the second flange in such a manner that the second buffer member is movable in the radial direction and limits axial deformation of the first and third buffer members.",
    "4. A connector according to claim 3, wherein the second buffer member is made from a substantially annular and flat metallic mesh material or spring steel material."

  "description_excerpt": "The present invention relates to a connector that is provided to a connection between a vibrating body and a plate-like shielding body attached to the vibrating body.\n\nEngines, transmissions, exhaust manifolds attached to engines, turbochargers, heat-exchanging components, and electrical rotating machines are vibrating bodies that themselves vibrate, or that are vibrated by being affected by engines. Various components are attached to such a vibrating body. One example of such attached components is a shielding body such as an exhaust manifold cover or a heat insulator.\n\nSuch a shielding body generally includes two metal sheets facing each other, and is configured to prevent physical energies such as heat and sound emitted from the vibrating body from being transmitted to other components near the engine or the outside of the vehicle. When the shielding body is vibrated by the vibrating body, either directly or indirectly, the shielding body may be damaged or generate unusual sound.\n\nTo avoid the effects of such vibrations, connectors have been conventionally developed for providing a vibration isolating structure to a connection between the vibrating body and the shielding body.\n\nPatent Document 1, for example, discloses a connector in which a buffer member including a spiral-shaped wire is interposed between a collar member and a member to be connected.\n\nPatent Document 1: Japanese Patent Publication 2011-64194-A\n\nThere are some possible problems in Cited Document 1.",
