Fluid pressure control device with cover for preventing misoperation

摘要

A cover 5 for preventing misoperation of an operating piece 3 for manual operation of a fluid pressure control device 1. Retaining grooves 7a and 7b are formed on the outer face of the plunger-type operating piece 3 which projects from the top face of the body 4 of the fluid pressure control device. The cover 5 is cylindrical and is provided with at least one hook 10 which is resiliently retained by the retaining groove 7a or 7b. A string-shaped connecting member 12 is connected to the operating piece 3, thereby preventing the cover 5 from being lost. The height of the cover 5 is set to be equal to or greater than that of the operating piece 3 in a non-operating position.
