Claims

[Claims for Utility Model Registration] 1. An actuating member that is shielded from the outside by a shielding wall of the main body and has a detected portion, and is magnetically coupled to the detected portion via the shielding wall, and A fluid pressure operated device comprising: an indicator that detects the position of the actuating member by sliding along with the movement of the actuating member; and a sliding surface on which the indicator slides, the indicator A fluid pressure operated device, wherein the indicator is slid on the sliding surface with opposing surfaces of the indicator and the sliding surface only partially in contact with each other. 2. The fluid pressure actuation according to claim 1, wherein a groove is formed on one of the opposing surfaces, the groove extending along the sliding direction of the indicator and reducing the contact area between the opposing surfaces. device. 3. Claim 1, wherein at least one cross-sectional shape of the opposing surface side transverse to the sliding direction of the indicator is a convex curved shape.
Fluid pressure actuated equipment as described. 4. The fluid pressure operated device according to claim 1, 2 or 3, wherein the indicator is plate-shaped.
