A fluid pressure cylinder comprising a cylinder tube, and a cover member (14, 16) fixed to an end of the cylinder tube, the fluid pressure cylinder including a pressure chamber (24, 26) formed between a piston and the cover member, wherein: a port (14a, 16a) configured to supply and discharge a pressure fluid to and from the pressure chamber, and a cushion hole (14b, 16b) configured to connect the pressure chamber and the port are provided in the cover member; a tubular cushion ring (28, 32) is attached to the piston or a piston rod so as to be insertable into and withdrawable from the cushion hole as the piston moves; a cushion packing (52, 54) having an annular shape and configured to slidably contact an outer circumference of the cushion ring is mounted in a mounting groove (14e, 16e) formed on an inner wall of the cover member constituting the cushion hole, the cushion packing being configured to be movable in an axial direction; the cushion packing includes a plurality of protrusions (52c, 54c) extending from an outer circumferential surface of the cushion packing to a side surface thereof near the piston, and disposed alongside one another in a circumferential direction; and a cushioning groove (30, 34) extending in a direction parallel to an axis of the cushion ring and having a cross-sectional area that changes is formed on an outer circumferential surface of the cushion ring, wherein the cushion packing includes an axially directed projection (52b, 54b) having an annular shape and configured to project out in an axial direction from a side surface of two side surfaces of the cushion packing that is farther from the piston; and the axially directed projection includes a cutout portion (52e, 54e) formed by cutting out a distal end part thereof at a predetermined position in the circumferential direction, and a flow path area of a passage formed by the cutout portion is smaller than a flow path area of a passage formed by a gap (52d, 54d) between adjacent ones of the protrusions. a port (14a, 16a) configured to supply and discharge a pressure fluid to and from the pressure chamber, and a cushion hole (14b, 16b) configured to connect the pressure chamber and the port are provided in the cover member; a tubular cushion ring (28, 32) is attached to the piston or a piston rod so as to be insertable into and withdrawable from the cushion hole as the piston moves; a cushion packing (52, 54) having an annular shape and configured to slidably contact an outer circumference of the cushion ring is mounted in a mounting groove (14e, 16e) formed on an inner wall of the cover member constituting the cushion hole, the cushion packing being configured to be movable in an axial direction; the cushion packing includes a plurality of protrusions (52c, 54c) extending from an outer circumferential surface of the cushion packing to a side surface thereof near the piston, and disposed alongside one another in a circumferential direction; and a cushioning groove (30, 34) extending in a direction parallel to an axis of the cushion ring and having a cross-sectional area that changes is formed on an outer circumferential surface of the cushion ring, wherein the cushion packing includes an axially directed projection (52b, 54b) having an annular shape and configured to project out in an axial direction from a side surface of two side surfaces of the cushion packing that is farther from the piston; and the axially directed projection includes a cutout portion (52e, 54e) formed by cutting out a distal end part thereof at a predetermined position in the circumferential direction, and a flow path area of a passage formed by the cutout portion is smaller than a flow path area of a passage formed by a gap (52d, 54d) between adjacent ones of the protrusions.
