Title: METHOD FOR PRODUCING PISTON ASSEMBLY AND HYDRAULIC FLUID DEVICE
Abstract:
A hydraulic fluid cylinder (10A) is equipped with a cylinder tube (12), a piston unit (18), and a piston rod (20). The piston unit (18) has a gasket (34) and a piston body (38) comprising a plurality of members and provided with a gasket-mounting groove (36). The piston body (38) has a first piston member (40) which projects to the outside from the piston rod (20), and also has a second piston member (42) positioned so as to be adjacent to the first piston member (40). The gasket-mounting groove (36) is formed from a combination of at least two members.
