The operation of the fluid pressure cylinder can be controlled simply by connecting the electric wire for 7a, and since the piping for supplying and discharging fluid to and from the rod side chamber 9 does not protrude outward from the cylinder body, other There is very little risk of interference with installed equipment. In particular, since the outer tube 6 is made of a steel tube with the same diameter as the rod cover 2 and head cover 3, there are almost no protruding parts in the circumferential direction and axial direction, and there is no impact.
It is durable against friction, vibration, heat, etc., and is difficult to break, and is unlikely to cause failures such as fluid leaks or malfunctions. Furthermore, since the cylinder tube 1 is covered by the outer tube 6, damage to the cylinder tube 1 due to falling tools and equipment is prevented. Therefore, since there is no need to consider damage caused by external force, the cylinder tube 1 can be made thinner. Further, the cylinder tube 1 is simply cylindrical and is fixed by caulking both ends of the outer tube 6, so the structure is simple and can be manufactured at low cost.

A horizontal hole 19 is bored in the longitudinal direction so as to pass through the shaft hole 18 from the circumferential surface, and a shaft portion 20 that fits into the shaft hole 18 is protruded from the center of the switching valve 17. The portion 20 has an engagement hole 2 at a position slightly closer to the switching valve side than the position corresponding to the horizontal hole 19.
0a is bored, and the horizontal hole 19 of the head cover 3
A taper pin 21 is provided which is driven across the engagement hole 20a of the switching valve 17, and a pull-out nut 21a is provided at the base of the taper pin 21.
A fluid pressure cylinder with a switching valve that is screwed together.
