構。[Claims for Utility Model Registration] In a valve mechanism for a compressor in which a port provided in a valve plate is opened and closed by a thin plate-like valve, the valve plate is composed of a plate body made of metal and a valve side of the plate body. a buffer layer made of an elastic material such as rubber provided on the surface of the plate; and an outer surface layer made of metal thinner than the plate body and provided on the upper surface of the buffer layer, the side of the outer layer corresponding to the valve. A compressor valve mechanism with a tapered surface that widens toward the valve side on the opening edge of the port.
