A fluid pressure cylinder comprising: a cylinder tube ; a piston slidably accommodated in the cylinder tube , the piston defining a rod side chamber in the cylinder tube ; a piston rod connected to the piston ; a port communicating with the rod side chamber , the port being configured to supply an operating fluid from an outside to the rod side chamber and discharge the operating fluid in the rod side chamber to the outside; a cushion bearing provided movably on an outer periphery of the piston rod , the cushion bearing being configured to narrow down the flow of the operating fluid discharged from the rod side chamber through the port when the piston rod reaches a stroke end; a limiting portion provided on the piston rod by facing the piston with the cushion bearing between them, the limiting portion being configured to limit movement of the cushion bearing in an axial direction; and a collar provided movably in a radial direction on the outer periphery of the piston rod between the cushion bearing and the limiting portion , wherein end surfaces of the cushion bearing and the collar faced with each other are inclined at an angle of less than 90 degrees symmetrically to a center axis of the piston rod , end surfaces of the limiting portion and the collar faced with each other are formed having plane shapes crossing the center axis; and the cushion bearing is configured to narrow down the flow of the operating fluid by entering a cylindrical portion provided on an inner periphery of the cylinder tube allowing the rod side chamber to communicate with the port , characterized in that the outer diameter of the collar is smaller than the outer diameter of the cushion bearing . a cylinder tube ; a piston slidably accommodated in the cylinder tube , the piston defining a rod side chamber in the cylinder tube ; a piston rod connected to the piston ; a port communicating with the rod side chamber , the port being configured to supply an operating fluid from an outside to the rod side chamber and discharge the operating fluid in the rod side chamber to the outside; a cushion bearing provided movably on an outer periphery of the piston rod , the cushion bearing being configured to narrow down the flow of the operating fluid discharged from the rod side chamber through the port when the piston rod reaches a stroke end; a limiting portion provided on the piston rod by facing the piston with the cushion bearing between them, the limiting portion being configured to limit movement of the cushion bearing in an axial direction; and a collar provided movably in a radial direction on the outer periphery of the piston rod between the cushion bearing and the limiting portion , wherein end surfaces of the cushion bearing and the collar faced with each other are inclined at an angle of less than 90 degrees symmetrically to a center axis of the piston rod , end surfaces of the limiting portion and the collar faced with each other are formed having plane shapes crossing the center axis; and the cushion bearing is configured to narrow down the flow of the operating fluid by entering a cylindrical portion provided on an inner periphery of the cylinder tube allowing the rod side chamber to communicate with the port , characterized in that the outer diameter of the collar is smaller than the outer diameter of the cushion bearing . <EOS>
