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 bonded body 1 includes a first member 10 having a hollow portion 13 with an opening in an end surface 11, and the second member 50 having a protrusion portion 53 protruding from a body portion 52, the protrusion portion 53 being accommodated in the hollow portion 13. An inner peripheral surface of the hollow portion 13 has an inclined portion 18 inclined to a radial direction of the opening of the hollow portion 13, and an outer peripheral surface of the protrusion portion 53 is in contact with the inclined portion 18. Alternatively, the outer peripheral surface of the protrusion portion 53 has a chamfered portion 54 inclined to the radial direction of the opening of the hollow portion 13, and the inner peripheral surface of the hollow portion 13 is in contact with the chamfered portion 54.
