A bonded body formed by frictional pressure-contact, includes: a first member including an end surface and a hollow portion with an opening in the end surface; and a second member including a body portion bonded to the end surface and a protrusion portion protruding from the body portion, the protrusion portion being accommodated in the hollow portion, wherein at least one of an inner peripheral surface of the hollow portion and an outer peripheral surface of the protrusion portion includes an inclined portion inclined to a radial direction of the opening, while the other is in contact with the inclined portion.

Bonded body, fluid pressure cylinder, and manufacturing method of bonded body

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

Fluid pressure cylinder

A device mounting structure for mounting a load maintaining mechanism on a hydraulic cylinder, a pipe for suppling and discharging working oil to and from the hydraulic cylinder being connected to the load maintaining mechanism such that the working oil is led thereto, includes a single coupling portion that includes a screw hole and is provided on the hydraulic cylinder, and a bracket to which the load maintaining mechanism is fixed, the bracket being coupled to the coupling portion via a first screw member that is screwed into the screw hole, wherein the bracket includes a first through hole through which the first screw member is passed so as to leave a gap in a radial direction.
