    • In the damper device, when the large diameter portion (51) does not apply an impact force on the flange portion (532), the elastic body (53b, 63b, 73b) is disposed in one of the housing (22) and the cylindrical portion with a gap and when the large diameter portion applies the impact force on the flange portion, the elastic body is compressed by the restricting surface and the flange portion in an axial direction to be deformed into a state that the elastic body is brought into contact with all of the housing, the restricting surface (52b, 62b), the cylindrical portion (531) and the flange portion to be filled in the gap. The impact receiving member (53a) is restricted from a movement relative to the housing by the deformed elastic body when the end portion (531 c) of the cylindrical portion (531) is advanced into the relief portion (52f, 62f, 72f) and the impact receiving member keeps a non-contact state with the housing.

    • The damper device (50) includes the shaft (21), the large diameter portion housing (52) and the impact absorbing member (53). When the large diameter portion does not apply an impact force on the flange portion (532), the elastic body (53b) is disposed at one of the inner peripheral surface (52c) of the housing and the outer peripheral surface (531 b) of the cylindrical portion (531) having a gap and when the large diameter portion applies the impact force on the flange portion, the elastic body is depressed in an axial direction to be deformed and is brought into contact with all of the inner peripheral surface of the housing, the restricting surface, the outer peripheral surface of the cylindrical portion and the flange portion. The impact receiving member (53a) is restricted from a relative movement relative to the housing by the deformed elastic body and the impact receiving member keeps a non-contact state with the housing.

    • The invention provides a shock-absorbing stopper capable of preventing an elastic body from contacting a mating component, such as a housing, to cause sliding wear as much as possible in a structure where a hollow is provided in the outer peripheral surface of the elastic body. In order to achieve the object, a shock-absorbing stopper has a cylindrical elastic body, to one end portion of which a fixed-side metal fitting is connected and to the other end portion of which a movable-side metal fitting is connected and which has an annular hollow in the outer peripheral surface of the cylindrical elastic body, in which the shock-absorbing stopper is sectioned into three portions by the hollow of a small diameter portion formed by the hollow, a fixed-side large diameter portion located closer to the fixed side relative to the hollow, and a movable-side large diameter portion located closer to the movable side relative to the hollow. The outer diameter dimension of the movable-side large diameter portion is set smaller than the outer diameter dimension of the fixed-side large diameter portion and the axial width of the movable-side large diameter portion is set smaller than the axial width of the fixed-side large diameter portion.
