路上に落下する危惧を防止する構造になっている。Conventional technology Figure 4.5 shows a conventional dynamic damper that is attached to functional parts such as the exhaust pipe and suspension that extend from the muffler of a car toward the rear of the car body, and absorbs and dampens the vibrations of these functional parts. This shows that. This dynamic damper is equipped with a bracket I. bracket l
In order to attach to a functional component (not shown), a screw insertion hole 1a is formed as a hole, and the weight 2 is connected via an elastic body 3 such as rubber or synthetic resin. In addition, the tip of the stay 4 connected to the side surface of the weight 2 is loosely fitted into a through hole 5 formed in the bracket l, and as the elastic body 3 is used, the connection between the bracket l and the weight 2 may come apart. In this case, the structure is such that the hook portion 4a formed at the tip of the stay 4 is coupled to the peripheral edge of the through hole 5 of the bracket l to prevent the weight 2 from falling onto the road.

形成した貫通孔５に遊嵌されている。A weight 2 is connected to the bracket I via an elastic body 3 such as rubber or synthetic resin. There is a stay 4 on the side of weight 2.
It is a combination of A. The tip of the stay 4A is loosely fitted into a through hole 5 formed in the bracket l.

A head 6 having a larger diameter than the through hole 5 is provided at the tip of the stay 4A that protrudes from the through hole 5 toward the side opposite to the weight 2. Specifically, the head 6 may be formed by, for example, forming one end of the stay 4A to bulge in the radial direction by press working, like making the head of a nail. With the head 6 provided, the stay 4A is inserted into the through hole 5 from the side opposite to the weight 2 of the bracket l, and is connected to the side surface of the weight 2 by a joining means such as welding. be.

Shake. If the connection between the bracket 1 and the weight 2 by the elastic body 3 dissociates over the course of use, the head 6 of the stay 4 is stopped at the periphery of the through hole 5 of the bracket 1, and the weight is fixed. 2 from falling onto the road.
