Abstract
A cylinder apparatus comprises a cylinder tube which is connected between a first cover member and a second cover member each having a cylindrical configuration, an axially displaceable piston which inscribes the cylinder tube, a piston rod which is connected to the piston, an intermediate member which is connected between the cylinder tube and the second cover member, an axially movable member which inscribes the intermediate member, a first spring member which is connected between the second cover member and the movable member, and a piston pin mechanism which is inserted into a recess of the piston rod in a direction perpendicular to the axis.
Claims6
A cylinder apparatus comprising:
- a cylinder tube which is integrally connected between a first cover member and a second cover member;
- a piston which is installed in said cylinder tube and which is axially displaceable in said cylinder tube;
- a piston rod which is connected to said piston;
- an intermediate member which is connected between said cylinder tube and said first cover member or said second cover member;
- an axially movable member which inscribes said intermediate member;
- a spring member which is interposed between said first cover member or said second cover member and said movable member;
- and
- a fastening mechanism which includes a pin section for holding said piston by being inserted into a recess of said piston rod in a direction substantially perpendicular to the axis of said cylinder apparatus,
- wherein when said piston reaches a displacement terminal end position, an axial length of a space is shorter than an axial distance between a side surface of said recess of said piston rod and a side surface of said pin section of said fastening mechanism, said space being defined between said intermediate member and said movable member.
