Abstract: A fluid pressure cylinder (1) includes two cylinder end walls (6',6"), a cylinder tube (2) and a piston (3), which is axially movable inside the cylinder tube, wherein at least one of the cylinder end walls is provided with an outward housing portion (7;60) and, located therein, an inward insert portion (8;61) which comprises a portion of at least one fluid channel belonging to the cylinder. The cylinder is distinguished in that the housing portion axially contacts the cylinder tube under force transmission, and that the insert portion includes an integral valve seat (12,16,22") of a fluid valve which is located in said fluid channel.
