Abstract
According to the present invention, in a casing having a casing member made of resin and a porous elastic member affixed onto the casing member, there is formed a thick wall portion, which is thicker than the other portions, at a bending corner portion formed between wall surfaces of the casing member. In this way, when the resinous casing member is molded, the resin in a melted state flows along a surface at an opposite side of the elastic member (at a side of an affixing surface between the casing member and the insulator), in a space for forming the thick wall portion. Therefore, the resin in the melted state is prevented from flowing to press upward an end portion of the elastic member at the corner portion. Accordingly, the defective 'reversing' is prevented so that the elastic member can be affixed on the wall surface of the casing member satisfactorily.
