摘要： An O-ring shaped annular rib (63) is disposed around the outer periphery of a flexible diaphragm member (62), and grooves (70, 71) are formed in first and second resin members (60, 61) for receiving the annular rib (63) in the compressed state. A hollow space is defined between the first and second members (60) for holding the diaphragm (62) in the clamped state. A contact surface (64) where the first and second synthetic resin members (60, 61) come into contact with each other, is located outward of the grooves (70, 71), and is subjected to welding with a supersonic welding tool (65). A gap (76) is formed between the first synthetic resin member (60) and the supersonic welding tool (65), which gap disappears as the welding progresses. At this time, further progress of the welding operation is inhibited by allowing the first synthetic resin member (60) and the supersonic welding tool (65) to provide a predetermined compression for the annular rib (63). Alternatively, a metallic spacer (77) is interposed between the first synthetic resin member (60) and the second synthetic resin member 61 with a gap (78) between the second synthetic resin member (61) and the metallic spacer (77) prior to a welding operation, which gap (78) disappears as the welding operation progresses, until further progress of the welding operation is halted.
