A spool is slidably installed in a valve hole of a valve body in which a plurality of ports are opened, and is made by fitting an annular packing that slides into the inner peripheral wall of the valve hole into a packing mounting groove on the outer periphery. , in which the fluid flow between the ports is switched by sliding of the spool, wherein the packing mounting groove in the spool is formed as having a locking projecting wall portion at an intermediate position of the groove side wall; The packing is composed of a main body part located on the outer circumference side of the ring and whose outer circumferential surface slides on the inner circumferential wall of the valve hole, and a retaining part located on the inner circumference side of the ring, which are integrally connected via a constriction part. A spool valve characterized in that a retaining portion of the packing is press-fitted into the bottom of the mounting groove and is locked to the protruding wall portion. 2. The spool valve according to claim 1, further comprising a shape-retaining protrusion on the side surface of the main body that abuts against the groove side wall of the mounting groove to prevent the main body from tilting due to deformation. 3. The spool valve according to claim 1 or 2, wherein a circulation groove through which fluid flows is cut in the radial direction on the side surface of the main body portion and the stopper portion.
