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 the spool is made of an annular packing that is fitted into a mounting groove on the outer periphery and that slides into contact with the inner peripheral wall of the valve hole. In a device in which the fluid flow between ports is switched by sliding of a spool, the above-mentioned packing is connected to the main body part located on the outer peripheral side of the ring and whose outer peripheral surface slides against the inner peripheral wall of the valve hole, and the groove side wall of the mounting groove. It consists of a retaining part with a seal lip that prevents fluid from flowing into the groove bottom space by coming into contact with the mounting groove, and a narrow fixing part that positions the inner circumferential part of the packing by tightly fitting into the mounting groove. The groove is configured such that the groove bottom side portion into which the fixing part of the packing fits is a narrow groove width part, and the upper end of the narrow width part is provided with a support step part that supports the seal lip from the groove bottom side. A spool valve characterized by:
