Hydraulic cylinder and quick coupler therewith
HYDRAULIC CYLINDER AND QUICK COUPLER THEREWITH A hydraulic cylinder (5) comprising: a cylinder tube (62); a piston rod (63) inserted into the cylinder tube (62) such that a longitudinal direction of the piston rod (63) extends in an extension and contraction direction of the piston rod (63); a piston (64) fixed to the piston rod (63), the piston (64) configured to slide on the inner circumferential surface (71 a) of the cylinder tube (62); and a spring member (94) disposed in the extension and contraction direction, the spring member (67) urging the piston rod (63) in the extension direction, wherein the piston rod (63) includes an opening (78a) and an internal space (78), the opening (78a) is held on an end surface (77b) on the contraction direction side of the piston rod (63), and the internal space (78) is formed from the opening (78a) in the extension direction, and the spring member (67) is inserted in the internal space (78).
