Some of them are provided with tapered or chamfered stress relaxation portions 56 and 57, respectively.
No. 4), the elastic body 53 provided with the grain or the concave portion 54 or the concave portion or the convex portion 55 on the entire inner peripheral surface and the entire outer peripheral surface between the hub 51 and the mass body 52 having such a pattern is formed in the axial direction. When press-fitting from one side, undulations occur in the rubber at the time of press-fitting, and the elastic body 53 is not inserted smoothly, so that the shaft 52 tends to run out as shown by the arrow in FIG. When the groove 58 is provided, the endless belt (not shown) wound around the pulley groove 58 may not smoothly rotate.
In addition to this, since the stress on the rubber sandwiched between the stress relaxation portions 56 and 57 is insufficient, the holding force (adhesive force) at that portion is insufficient, and the portion is easily peeled and the stress is easily concentrated. Thus, the effect of the stress relaxation shape is reduced.

ｍｍ程度あれば充分である。The elastic body 3 is formed into an annular shape by a predetermined rubber, and is elastically connected between the hub 1 and the mass body 2 by being press-fitted between the hub 1 and the mass body 2. As shown in FIGS. 2 and 3, a concave portion for holding an adhesive or lubricating oil (neither is shown) is provided over the entire surface of the elastic body 3 in contact with the cylindrical surface portions 6, 8. 1
In the same manner, an annular smooth surface 11 having no unevenness is provided at a portion of the elastic body 3 in contact with the stress relaxation portions 7 and 9. The recess 10 is an elastic body 3
The smooth surface 11 is also provided on the inner circumferential surface and the outer circumferential surface of the elastic body 3, respectively. The smooth surface 11 is provided on each of the inner peripheral surface and the outer peripheral surface of the elastic body 3 at both ends in the axial direction. 1 and 2, the portions of the elastic body 3 that are in contact with the stress relaxing portions 7 and 9, that is, the axial width of the smooth surface 11 are indicated by reference signs x 1 and x 2.

の効果を充分に引き出すことができる。When assembling the torsional damper having the above structure, first, a liquid adhesive is applied to the inner and outer peripheral surfaces of the elastic body 3, respectively, and then the adhesive is applied. It is press-fitted between the hub 1 and the mass body 2 from one side in the axial direction. Since the smooth surface 11 is provided at the end of the elastic body 3, the press-fitting is less likely to cause undulation in the rubber, and thus can be easily performed. A large amount of the adhesive applied to the elastic body 3 is held in the recess 10, so that the hub 1
And the elastic body 3, and the mass body 2 and the elastic body 3 can be firmly connected. After the press-fitting, a relatively large portion of the volume having the annular smooth surface 11 having no irregularities is interposed between the hub 1 and the stress relaxing portions 7 and 9 of the mass body 2. 2 can be sufficiently supported so as not to cause shaft runout, and the stress relaxation portions 7 and 9 can be supported.
Effect can be fully obtained.

もできる。Further, as in the above-described prior art, a concave portion is formed on the entire inner peripheral surface and the entire outer peripheral surface of the elastic body, and the elastic body is strongly bonded to the stress relief portion of the hub and the mass body. However, according to the torsion damper having the above structure, the smooth surface 11 has a low wettability and a small adhesive force to the stress relaxing portions 7 and 9. The generation of such cracks can be effectively prevented. Further, the insertability of the elastic body 3 into the jig at the time of press fitting can be improved.

かつ滑りトルクを増大させることもできる。When lubricating oil is applied to the inner and outer peripheral surfaces of the elastic body 3 instead of the adhesive,
Since a large amount of the applied oil is held in the concave portion 10, the elastic body 3 can be easily pressed into a narrow space between the hub 1 and the mass body 2. In addition, a relatively large portion of a volume having an annular smooth surface 11 having no irregularities is interposed between the hub 1 and the stress relaxation portions 7 and 9 of the mass body 2, so that the mass body 2 has a shaft. This can be sufficiently supported so as not to cause runout, and the effects of the stress relaxation portions 7 and 9 can be sufficiently brought out. Further, the insertability of the elastic body 3 into the jig at the time of press fitting can be improved,
In addition, the slip torque can be increased.

Further, a groove-shaped depression is included, and examples of the groove-shaped depression include a groove whose longitudinal direction is oriented in the axial direction as shown in FIG. 4 and a spiral groove as shown in FIG. it can.

The convex portion is formed by pressing the elastic body 3 between the hub 1 and the mass body 2 and pressing the elastic body 3 on the surface of the elastic body 3. By taking advantage of the fact that a relative concave portion may be provided around the convex portion when the portion is compressed and immersed, an adhesive or oil is held in the relative concave portion.
