| 摘要 | A fluid pressure damper is provided with a damper main body composed of an outer tube and an inner tube, a bottom member for sealing a bottom side opening of the damper main body, a suspension spring and a damper. The damper includes a cylinder storing a working fluid inside. The cylinder is inserted into the inner tube and fixed to the bottom member by being sandwiched between a head member fixed to a joint member coupled to the inner tube and the bottom member. The joint member includes a stopper member with the inner periphery of which the head member is threadably engaged, and a pin member which couples the stopper member to the inner periphery of the inner tube. The suspension spring is supported by the stopper member. | ||
