Abstract: A pair of recesses is formed on a cylinder hole of a cylinder tube, wherein the recesses are recessed further into the cylinder hole from an inner circumferential surface thereof. Projections that correspond to the recesses are disposed on a head cover and a rod cover, respectively, which are installed into both ends of the cylinder tube. The head cover and the rod cover that are accommodated in the cylinder hole are positioned through abutment of the projections against stepped portions of the recesses.

Abstract: A cylinder tube includes a cylinder hole therein through which a piston is displaceably inserted. A head cover and a rod cover are installed respectively into ends of the cylinder hole. Locking rings, each having a bent section, a pair of arm sections that extend from both ends of the bent section, and claw sections disposed on ends of the arm sections, are disposed in the cylinder hole. In addition, the locking rings are installed respectively in the cylinder hole through ring grooves, wherein the head cover and the rod cover are fixed by means of the locking rings.

Abstract: The present invention provides a switch mounting mechanism that can be adopted with ease in conjunction with a compact fluid pressure device. A space (31), to be used to absorb elastic deformation of a holding arm (33) occurring as a switch holder (24) is inserted through a groove opening (22A) of a switch mounting groove (22), is formed. A clearance (32) to be used as a buffer for the holding arm (33) is formed between the switch mounting groove (22) and a detection switch (21). As a result, the switch holder (24) can be inserted to assume the same position as the detection switch (21) inside the switch mounting groove (22).

Abstract: A piston is slidably displaced inside of a cylinder tube, and damper grooves are provided on both end surfaces of the piston, which extend substantially perpendicular to the axis thereof. The damper grooves penetrate along the end surfaces of the piston, and respective dampers formed from an elastic material are installed therein. On the dampers, base members thereof are inserted into first grooves that make up the damper grooves, and guide members, which are expanded in width with respect to the base members, are inserted into second grooves that lie adjacent to and are expanded in width with respect to the first grooves.
