    摘要： A fluid pressure cylinder includes a cylinder tube, a piston and a solid piston rod. The piston rod includes a head-side passage defined by a head-side shaft hole extending in an axial direction, a head-side outer hole open on a part projecting from the cylinder tube and a head-side inner hole open to a head-side chamber and allowing communication between a head-side chamber and a fluid pressure source, and a bottom-side passage allowing communication between a bottom-side chamber and the fluid pressure source. The head-side shaft hole includes an opening end and a tip formed inside the piston rod. The opening end of the head-side shaft hole is sealed by a sealing member.

    摘要： a fluid pressure cylinder 100 includes a cushion bearing 60 provided movably on an outer periphery of the piston rod 30; a flange portion 38 provided on the piston rod 30 by facing the piston 20 with the cushion bearing 60 between them; and a collar 70 provided movably in a radial direction on the outer periphery of the piston rod 30 between the cushion bearing 60 and the flange portion 38. End surfaces 60b, 70b of the cushion bearing 60 and the collar 70 are inclined symmetrically to a center axis of the piston rod 30, and end surfaces 38a, 70a of the flange portion 38 and the collar 70 are formed having plane shapes crossing the center axis.

    摘要： A rotary valve that controls a flow rate at which working oil is supplied to and discharged from a hydraulic cylinder (20) that causes a wing (2, 3) to rotate about a rotary shaft (5) includes a rotor (60) that rotates as the wing (2, 3) rotates about the rotary shaft (5), and a first control flow passage (61) and a second control flow passage (65) formed in the rotor (60) to control the flow rate at which the working fluid is supplied to and discharged from the hydraulic cylinder (20), wherein the first control flow passage (61) and the second control flow passage (65) respectively vary a resistance exerted on a flow of the working fluid passing therethrough as the rotor (60) rotates.
