を形成したことを特徴とするスプール弁。[Scope of Claim for Utility Model Registration] A spool is slidably installed in a valve hole of a valve body in which a plurality of ports are opened, and is made up of an annular packing that is fitted into a mounting groove on the outer periphery and is in sliding contact with the inner circumferential wall of the valve hole. The fluid flow between the ports is switched by the sliding of the spool, characterized in that the packing is provided with a seal lip that comes into contact with the groove side wall of the mounting groove and prevents fluid from flowing into the groove bottom space. spool valve.
