<p>PURPOSE:To prevent the generation of shock noise and to favorably keep regular torque transmission by restraining the axial displacement of the outer peripheral portion of a hub when a torque transmission and buffer elastic element disposed between the shaft portion and the outer peripheral portion of the hub is axially eccentric. CONSTITUTION:An output hug 4 is divided into an outer peripheral portion 4a disposed axially adjacent to a cylindrical portion 1a of an input rotor 1 and a hub shaft portion 4b disposed at space on the inner peripheral side of the outer peripheral portion 4a. The hub outer peripheral portion 4a and the hub shaft portion 4b are connected in a body by an elastic element 13 such as rubber or the like. Elastic element stoppers 16, 17 are disposed on a spring cover 7 and a discoidal projecting portion 42 of the hub shaft portion 4b that confront with both sides of the hub outer peripheral portion 4a. Accordingly, the elastic element stoppers 16, 17 can prevent the axial eccentricity of the elastic element 13 and the axial displacement of the hub outer peripheral portion 4a.</p> |
