ABSTRACT:
In a fluid pressure control device such as a solenoid-controlled valve having an operating piece for manual operation which is a selector-type operating piece, a cover for preventing misoperation is attached to the selector-type operating piece. Consequently, a cover 6 for preventing misoperation comprised of a base part 10 having an attaching part 14 to be fixed to the casing and a lid part 11 which is integrally connected with the base part 10 via a bending part 12 which can be bent and stretched is attached to a selector-type operating piece 5 having a handle 5a for manual operation at the top. By bending the bending part 12, the lid part 11 can be closed between a closed position covering the handle 5a and opened an open position to release the handle 5a.
