Conventionally, as an example of this type of damper, as shown in FIG. A composite type rim comprising a first damper section 4 that mainly absorbs torsional vibrations on the outer periphery and a second damper section 8 that mainly absorbs bending vibrations located on the inner periphery of the rim 3. Dampers are known. First damper section 4
An elastic body 7 is vulcanized and bonded between the vibrating ring 5 and the sleeve 6 to form a three-layered bushing, and the damper portion 4 is previously formed into this bushing structure and then fitted onto the rim 3. On the other hand, the second damper section 8 has a vibration ring 9 and an elastic body 10, and the elastic body 10 is directly vulcanized and bonded to the hub 1.

In the damper according to the above-mentioned prior art, the second damper part 8, which is mainly responsible for absorbing bending vibration, is located at the hub 1.
The elastic body 10 and the vibration ring 9 are connected side by side in the axial direction, and as shown in the figure, the shape is such that the vulcanization bonding surface cannot be sufficiently wide.
For this reason, the damper portion 8 is in a situation where the elastic body 10 is particularly susceptible to breakage, and if the elastic body 10 breaks for some reason, the vibration ring 9 will fly out to the left in the figure, creating the risk of an unexpected accident. . In order to cope with this, the damper has a stopper ring 11 prepared in advance, and the stopper ring 11 is fitted around the circumference of the rim 3 to prevent the vibration ring 9 from popping out.

出し防止策が採られていない。 In the prior art, the stopper ring 11 is prepared as a separate dedicated member solely for the purpose of preventing the vibrating ring 9 from popping out, and although this objective can be achieved, it also increases the number of parts and the press-fitting process. is bringing about. Furthermore, although the possibility of the first damper portion 4 being relatively small, there is a risk that the elastic body 7 may break and the vibrating ring 5 may pop out. Conventionally, no measures have been taken to prevent this vibrating ring 5 from popping out. Not taken.

In view of the above points, the present invention has been devised to solve the problems seen in the above-mentioned prior art.
To achieve this purpose, in a composite damper in which a plurality of vibration rings are connected to one hub through elastic bodies, a bush is constructed by adding a sleeve to at least one set of vibration rings and elastic bodies. A stopper piece is integrally formed on the sleeve to prevent the vibrating ring belonging to the own set and the vibrating ring belonging to another set from popping out.

９が衝接したときに緩衝作用をはたす。 The sleeve 6 is formed from a rolled steel plate such as SPC material, but various metals and resin materials may be used for the material. FIG. 2 shows, as an example, the sleeve 6 molded from cast iron, and stopper pieces 12 and 13 are attached to the vibration rings 5 and 9 of both the first and second damper parts 4 and 8, respectively. are integrally molded. In addition, each stopper piece 1 is common to Fig. 1 and Fig. 2.
2 and 13 are shown in an annular shape in the figure, but it is not necessary that the stopper pieces be annular, and a large number of stopper pieces may be arranged in an equidistant manner or in an irregular manner in the circumferential direction. When a large number of stopper pieces are arranged in the circumferential direction in this way, the stopper pieces have a spring force that swings in the axial direction depending on the material, and the vibration ring 5,
9 acts as a buffer when there is a collision.
