In this example, a support ring having a C-shaped cross section made of spring steel having a diameter slightly larger than the inner diameter of the shaft body and having a notch in a part thereof is provided, and a plurality of rubber bodies are interposed by the support ring. The inner weight (weight for damping) is elastically supported at the center, and the damping member (dynamic damper) configured in this way temporarily changes its shape in the diametrical direction by the spring force of the support ring. The hollow shaft is fitted in a compressed form and is fixed in the shaft by utilizing the spring force.

中空部７Ａの内径よりも大きく設定されている。The vibration damping device 1 according to the present invention is press-fitted into the hollow portion 7A of the shaft 7 at a predetermined position. Therefore, the outer diameter of the support ring 2 is somewhat smaller than the inner diameter of the shaft hollow portion 7A. It is preferably formed to be suitable for a clearance fit. On the other hand, the first engaging portion 2 of the support ring 2
The diameter of the outer peripheral portion of the annular protrusion 3 provided in B is equal to that of the support ring 2.
Is sufficiently larger than the outer diameter of the shaft hollow portion 7 and the diameter of the end portion 2D of the first engaging portion 2B, which has a narrowed shape, does not hinder the press-fitting into the shaft hollow portion 7A.
It is desirable to keep the diameter somewhat smaller than the inner diameter of A. Further, the outer diameter of the end 2E of the second engaging portion 2C is set to be larger than the inner diameter of the hollow shaft portion 7A.

The first engaging portion 2B and the second engaging portion 2C exert their respective spring forces, and in particular, the annular protrusion 3 of the first engaging portion 2B and the end 2E of the second engaging portion 2C are the shaft hollow portion 7A. By virtue of strong linear pressure contact with the surface of the vibration damping device 1, the vibration damping device 1 can be stably fixed at a desired position of the hollow shaft portion 7A. When the end 2D of the first engaging portion 2B is applied to the loading side of the shaft 7 and a force is applied to the vibration damping device 1 in the direction of arrow P (see FIG. 1) using a jig or the like, the first engaging portion The portion 2B becomes narrowed through the cut groove 4B, and the vibration damping device 1 itself is pushed in such a manner that the annular protrusion 3 is in pressure contact with the inner peripheral surface of the hollow shaft portion 7A. Further, the second engaging portion 2C also has a shape in which it is similarly squeezed with the pushing operation, and can be fixed at a desired position as shown in FIG.

Since they are pressure-contacted with each other, the pressure-contact force generated by the spring force of both engaging portions 2B, 2C is strengthened by the line contact, and the vibration damping device itself is weakened by the spring force as in the conventional example. It is prevented that the hollow portion 7A of 7 rotates idly and the damping force is impaired.

And annular protrusions 3B and 3 on the second engaging portion 2C, respectively.
C is projected, and both ends are squeezed. Therefore, in the case of this example, when the vibration damping device 1 is press-fitted into the hollow portion of the shaft, the first engaging portion 2
Press-fitting becomes easy even if either the end 2D of B or the end 2E of the second engaging portion 2C is the head. In this example, the press-fitting causes the annular projections 3B and 3C to linearly press contact with the inner peripheral surface of the hollow shaft portion 7A. Further, it is possible to hold the spring force evenly and firmly at both ends and to fix the shaft hollow portion at any position. Furthermore, it becomes easy to press fit into a narrow shaft.

Although it is possible to reduce the resistance at the time of press-fitting No. 1, if it is too loose, the spring force at the time of press-fitting and fixing will be weakened. Therefore, the inclination angle of the tapered surface can be set in consideration of both of these points. desirable.

An engaging portion having an outer diameter larger than the inner diameter of the same and having a spring action capable of expanding and contracting in the radial direction is formed, and the support ring is engaged and fixed to the hollow portion of the shaft by the spring action of both engaging portions. Therefore, the support ring can be mounted and fixed at a free position in the hollow portion of the shaft, and the first and second spring-attached portions provided at both ends of the support ring can be used to fix the shaft . Since it can be pressed into contact with the inner peripheral surface of the hollow portion in the form of line contact, the engaging force is carried through both ends, the vibration damping device spins in the shaft, and the vibration damping function is impaired. Can be prevented. Further, even if the spring force of one engaging portion is reduced due to heat or the like, the spring force of the other engaging portion causes the vibration damping device to idle,
It is possible to prevent the damping function from being impaired.
