In the valve mechanism, the valve body 1
Gap G between the inner surface of the valve chamber 2 and the outer periphery of the valve body within the movement range of
is set narrowly so that the valve is maintained in an open state until the pressure difference is substantially eliminated, and a flow path 3 is formed inside the valve chamber to release the airflow that causes the valve body 1 to open. Valve squeal prevention device. (2) In the valve mechanism according to claim 1, the flow passages 3 are groove-shaped recesses formed in the movement direction of the valve body, and are arranged in large numbers at predetermined intervals in the inner circumferential direction of the valve chamber 2. Valve squeal prevention device. (3) The valve squeal prevention device in a valve mechanism according to claim 1 or 2, wherein the starting end of the flow path 3 is at or near the position of the valve body 1 in an open state. (4) A valve squeal prevention device in a valve mechanism according to claim 1, wherein the valve body acts as a positive pressure valve.
