Abstract
The damper device includes the shaft, the large diameter portion housing and the impact absorbing member. When the large diameter portion does not apply an impact force on the flange portion, the elastic body is disposed at one of the inner peripheral surface of the housing and the outer peripheral surface of the cylindrical portion having a gap and when the large diameter portion applies the impact force on the flange portion, the elastic body is deformed 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 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.
