Abstract:
An air-flow control valve of the structure in which a soft foamed sheet (2) is joined to one or both surfaces of a valve body (1) made of a synthetic resin as a unitary structure via a sheet (3) for preventing the oozing of resin. The ooze-preventing sheet (3) is stuck with an adhesive or the like onto one surface of the soft foamed sheet (2) in advance, and a synthetic resin for forming the valve body (1) is placed on the stuck surface of the foamed sheet (2). Or, another foamed sheet (2) with its sticking surface being on the lower side is further placed thereon, followed by stamping. Therefore, the foamed sheet (2) is not peeled off, and the air-flow control valve exhibits sufficient buffer function against the rigid valve body (1).
