接合装置
Document Type and Number:
Japanese Patent JP7365998
Kind Code:
B2
Abstract:
To provide a joint device which reduces work for earth connection of an electric motor and an external device and design study.SOLUTION: A joint device S that joins a conductive external device to a case of a grounded motor includes: a head part B1; a screw part B3; a conductive bolt B provided with a substantially conical tapered part B2 that tapers toward the screw part B3 between the head part B1 and the screw part B3; a flat-shaped outer peripheral part W1 in which a hole into which the bolt B is inserted is formed in the center; and a cylindrical-shaped upright part W2 that is bent from the outer peripheral portion W1 and is formed along the hole. The upright part 2 is provided with a conductive washer W having at least one protrusion part W3 protruding in an outer peripheral direction, and the tapered part B2 abuts the upright part W2, and the case and the external device come into contact with each other to be electrically conductive, when the bolt B is screwed to the case via the washer W to join the case and the external device.SELECTED DRAWING: Figure 5
