Document Type and Number:
Japanese Patent JP3659839
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve yield of material of a bottom and a piston and to simplify structure in a fluid pressure cylinder used as a lift cylinder or the like of a forklift truck and provided with a cushion function.
SOLUTION: This fluid pressure cylinder is constituted of a cylinder tube 2, a bottom 3, a piston 4, a piston rod 5, a supply and exhaust port 6, a seat 7, a cylinder hole 8, and a valve element 9. In this case, the piston rod 5 is provided so as to penetrate the piston 4 and the piston 5 is formed with the cylinder hole 8 to which the valve element 9 is provided to be movable.
