Title:
FLUID PRESSURE DEVICE AND METHOD FOR MANUFACTURING PISTON ASSEMBLY
Document Type and Number:
Japanese Patent JP2018025243
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily improve productivity of a fluid pressure device.SOLUTION: A fluid pressure cylinder 10A includes a cylinder tube 12, a piston unit 18, and a piston rod 20. The piston unit 18 includes packing 34, and a piston body 38 consisting of a plurality of members and in which a packing attachment groove 36 is provided. The piston body 38 includes a first piston member 40 projecting outward from the piston rod 20, and a second piston member 42 arranged adjacently to the first piston member 40. The packing attachment groove 36 is formed by combination of at least two members.SELECTED DRAWING: Figure 1
