PROBLEM TO BE SOLVED: To suppress deterioration in vehicle mountability accompanied with an increase in the scale of a damper while making a damper function be maintained even when a large impact load is applied to the damper.SOLUTION: In a vehicle in which a universal joint 21 and a damper 30 are provided on a drive shaft 10 at an interval in an axial direction, the damper 30 is provided with: a cylindrical part 32 having an opening portion 32b at the tip; a shaft part 50 with the tip portion accommodated in the cylindrical part 32; an elastic member 60 interposed between the shaft part 50 and the cylindrical part 32; a bearing 38 interposed between the outer periphery of the shaft part 50 and the inner periphery of the cylindrical part 32 at an axial position closer to the opening portion side than the elastic member 60; a diameter expansion part 54 protruding radially outward from the outer periphery of the shaft part 50 at an axial position closer to a side opposite to the opening portion than the bearing 38; and a retaining part 42 protruding radially inward from the inner periphery of the cylindrical part 32 at an axial position closer to the opening portion side than the bearing 38. Retaining strength of the damper 30 by the retaining part 42 is set larger than retaining strength of the universal joint 21. |
