A guide ring is provided at a sliding portion between the valve stem and the valve body to guide the valve stem. At the same time, a seal ring for sealing between the valve stem and the valve body is disposed in a seal groove formed across the valve stem and the valve body, and the seal ring has a long cross section in the radial direction. It has a flat annular shape, and its inner and outer circumferential surfaces are in fluid-tight contact with the inner and outer circumferential surfaces of the seal groove, respectively, and as the valve stem slides, the inner circumferential portion moves in the axial direction of the valve stem. The groove part on the valve body side that constitutes the seal groove has an annular support in which the tip of the inner hole has a large diameter within the large diameter part formed at the end of the valve hole. A poppet-type switching valve characterized in that the valve body is formed between the valve body and the support member by fitting members.
