角θ３を、 θ＜θ１≦θ２≦４５°，θ３≧０° とした、 ことを特徴とするスプール弁。[Scope of Claim for Utility Model Registration] A valve seat consisting of a valve housing and a valve stem slidably inserted in the axial direction inside the valve housing, and located between an input port and an output port on the inner wall of the valve housing. The annular elastic valve body fitted into the outer circumferential groove of the valve stem is integrated with a mounting portion that fits into the outer circumferential groove and a bent portion extending radially from the mounting portion. The bent portion is formed by making the length in the radial direction larger than the thickness in the axial direction, and the valve body is brought into contact with the valve seat by sliding from the output port side in the valve housing, thereby forming a bridge between both ports. In the spool valve configured to open and close, a tapered surface is formed at the end of the inner wall of the valve housing on the output port side of the valve seat, the bent portion of the elastic valve body is inclined toward the valve seat side, and the tapered surface is The angle θ 1 formed with the axis, the angle θ 2 at which the bent portion is inclined with respect to the plane perpendicular to the axis, and the angle θ 3 formed between the sealing surface at the tip of the bent portion and the tapered surface, θ<θ 1 ≦ A spool valve characterized in that θ 2 ≦45° and θ 3 ≧0°.
