Claims (1)

[Claims for Utility Model Registration] (1) In a structure in which a first member and a second member are connected using bolts or screws, a damping body is attached to the bolt or screw, and the first member and a second member are connected by bolting or screwing, the damping body is interposed between the contact surfaces of the bolt or screw and the first and second members. Vibration damping structure featuring (2) Consisting of a bolt or screw that is inserted into the mounting holes of the first and second members, a nut that is screwed into the threaded part, and a cylindrical damping body that has flanges at both ends, and the damping body When the vibrating body is attached to the bolt or nut, and the first and second members are connected by tightening the bolt or screw and the nut,
The damping body is interposed between the head and threaded portion of the bolt or screw, the nut, and the mounting holes of the first and second members and the contact surfaces of the peripheral edges thereof. A vibration damping structure characterized by: (3) One collar part of the damping body is interposed between the head of the bolt or screw and the periphery of the mounting hole of the first or second member, and the cylindrical part is connected to the bolt or screw part and the mounting hole. and the other collar portion is interposed between the nut and the periphery of the attachment hole of the second or first member by tightening the screw to the threaded portion of the nut. The vibration damping structure according to claim 2, characterized in that: (4) The vibration damping body is formed with a three-layer structure in which rubber-based resin is interposed between two metal plates, and when the nut is tightened, the other brim side is pushed out and deformed. Claim 2 or 3 characterized in that
Vibration damping structure described in. (5) In a structure in which the first and second members are bolted or screwed together using a bolt or screw, a nut, and a washer assembled to the head side of the bolt or screw, the washer is attached to two metal sheets. A vibration damping structure characterized by a three-layer structure with rubber-based resin interposed between plate materials. (6) forming a mounting boss on the first or second member;
In the structure in which a second or first member is screwed and fixed to the first or second member via this mounting boss, the mounting boss and either one of the second or first member are in contact with each other. A vibration damping structure characterized in that a plurality of protrusions are provided on a surface so that the mounting boss and the mounting surface of the second or first member come into contact with each other via the protrusions.
