<p>A reed valve (11) includes a vibration suppressing member (15a, 18a) for suppressing transmission of vibration, caused due to opening and closing operations of a reed piece (17), to a fixed mounting portion of an engine part to which the reed valve is mounted. The vibration suppressing member includes an elastic annular projection (15a) formed on at least one of an outer peripheral surface of a gasket (15) fitted around an outer peripheral edge (12a) of a valve plate (12) and a pair of upper and lower surfaces of the gasket. The elastic annular projection is elastically engaged with the fixed mounting portion when the mount portion (12a) of the valve plate (12) is mounted to the fixed mounting portion. <IMAGE></p>
