Abstract:
1. A cylinder device comprising: a housing; a slidable shaft which is slidably movably disposed inside the housing and projectable out of the housing; a joint member connected to the end section of the slidable shaft; and a stopper member disposed at a joint section between the slidable shaft and the joint member so as to be brought into contact with an end section of the housing to stop a relative slidable movement between the slidable shaft and the housing and to provide a buffering function during contact of the slidable shaft to the housing; wherein the end section of the slidable shaft is partially cutout to form an axial engagement surface exposed at a tip end of the slidable shaft including an end face whose surface area is smaller than a cross-sectional area of the end section; the slidable shaft and the joint member are connected to each other in a condition where the end face of the slidable shaft is in contact with an end face of the joint member so that a groove is formed between the axial engagement surface of the slidable shaft and the end face of the joint member; and the stopper member is formed annular to have an opening so as to be mountable on an outer peripheral surface of the slidable shaft and has an engagement section formed along an inner periphery of the stopper member, the engagement section of the stopper member being fitted in the groove so that the stopper member is prevented from at least an axial movement.
