の抑留装置。Inside the detent case, which is housed in a case fixed to the end of the housing and has an annular projection at a predetermined position on the inner peripheral surface,
A cylinder is fixed to the end of the spool which is elastically supported so as to return to the neutral position when budding, and has a plurality of holes in a predetermined position on the peripheral wall, and a spring is fitted into the cylinder so as to be movable in the axial direction. The balls loosely fitted in the name tag of the cylindrical body are pushed outward by the conical body which is pressed in the distal direction, and at the position where these balls pass over the annular protrusion, the balls and the annular protrusion cooperate with each other. In a restraining device for a manual switching valve that restrains the spool, the cone is supported movably in the axial direction by a bolt screwed onto the end of the cylindrical body, and the moving position of the cone is controlled by the head of the bolt. A restraining device for a manual switching valve, characterized in that a slight gap is provided between the inner peripheral surface of the detent case and the ball.
