閉装置。An enlarged diameter portion is formed on the rim of a valve port provided in the valve box, and a fitting portion that loosely fits into the enlarged diameter portion is provided at the tip of a valve rod arranged concentrically with the valve port in the valve box. A pressing surface corresponding to the rear end surface of the enlarged diameter part is formed, and a cylindrical seal made of an elastic material is fitted into the enlarged diameter part or the fitting part, and when the valve rod enters the valve port, the pressure is applied. The valve port is sealed by compressing the seal in the axial direction between the inner end surface and the pressing surface and expanding it in the radial direction so as to make elastic contact with the enlarged diameter part and the fitting part. A valve opening/closing device for a poppet valve characterized by:
