  "abstract": "A drawn portion having a shape protruding from a side face to a space inside a housing is provided at an end to which a rear surface cover is fastened of the side face. On a side to which the rear surface cover is fastened of the drawn portion, a bent portion having a shape bent toward a space outside the housing is provided. A screw receiving portion including a screw hole includes a first receiving surface, which is a flat surface portion on an end of the bent portion, and a second receiving surface having a shape protruding from a base of the bent portion.",
  "claims": [
    "1. A vehicle-mounted electronic apparatus comprising: a screw fastening structure which fastens, to a first face of a metal housing, a second face, wherein the screw fastening structure is provided with a drawn portion having a shape protruded from the first face to an inside of the metal housing, the drawn portion provided at an end of the first face, the second face fastened to the end of the first face, a bent portion having a shape bent toward a space outside the metal housing, the bent portion provided on a side of the drawn portion, the second face fastened to the side of the drawn portion, and a screw receiving portion including a screw hole, the screw receiving portion formed of a first receiving surface, which is a flat surface portion on an end of the bent portion and is perpendicular to the first face, and a second receiving surface having a shape protruded from a base of the bent portion, the second receiving surface perpendicular to the first face.",
    "2. The vehicle-mounted electronic apparatus according to claim 1, wherein the screw fastening structure includes a protrusion provided on a portion of the drawn portion, the portion of the drawn portion opposed to the screw receiving portion, the protrusion abutting the screw receiving portion."

  "description_excerpt": "The present invention relates to a vehicle-mounted electronic apparatus.\n\nIn a case where a member to be fastened is fastened to a metal housing using a screw, it is necessary to prevent a metal foreign matter generated at the time of screw fastening from entering the metal housing. In some vehicle-mounted electronic apparatuses, an installation space on a vehicle is determined in advance, as exemplified by a vehicle navigation device that fits into a dashboard. The metal housing of such vehicle-mounted electronic apparatus needs to be designed in such a manner as to fit into the installation space, and thus such vehicle-mounted electronic apparatus cannot have a screw fastening structure in a position protruding from the metal housing. Therefore, for example, Patent Literature 1 proposes a screw fastening structure in which a drawn fastening portion having a lower surface and an upper surface integral with each other is provided on a bottom surface of a metal housing. This drawn fastening portion includes an outer edge that extends from the upper surface and that is bent outward in such a manner as to be opposed to a fastened member. On the outer edge, a screw hole is formed in a position which corresponds to the outer side of the metal housing and which is lower than the upper surface. Since a tip of a screw that fastens the fastened member to the outer edge protrudes outside the metal housing, a metal foreign matter generated at the time of screw fastening does not enter the metal housing.",
