Zusammenfassung:	PURPOSE:To permit to display sufficient shock absorbing property with respect to the rigidity of valve main body without separating foam sheets by a method wherein the soft foam sheets are connected integrally to one or both surfaces of the main body of the valve made of synthetic resin through impregnation preventing sheet layers for resin. CONSTITUTION:The soft foam sheets 2 are connected integrally to one or both surfaces of the main body 1 of valve made of synthetic resin. In this case, said impregnation preventing sheet 3 is bonded by a bonding agent onto one surface of the soft foam sheet 2 previously and synthetic resin 1' for forming the valve main body is put on the bonding surface of the foam sheet 2 and the foam sheet 2 is put thereon so that the bonding surface is faced downward, thereafter, the valve is formed by stamping. According to this method, the excellent air stream control valve may be provided by only utilizing simple stamping forming method and the manufacturing operation may be effected continuously.
