    摘要： The invention improves a brazing filler metal coming around a portion between a flow channel pipe connected to a side surface of a valve main body and the valve main body, and enhances a joint strength of the flow channel pipe. A valve gear is provided with a valve main body (13) which is provided in an inner portion with a valve chamber (14) having a valve seat (23), a valve body (17) which moves forward and backward with respect to the valve seat, a first flow channel pipe(15) and a second flow channel pipe (16) which are connected to the valve main body in such a manner as to communicate with the valve chamber, and a drive unit (41) which drives the valve body, in which the valve main body is constructed by a tubular member, and has an opening hole (24) for connecting the first flow channel pipe in a side wall (13a) thereof, and the first flow channel pipe is fixed to the opening hole by brazing, wherein a gap between an inner peripheral surface of the opening hole and an outer peripheral surface of the first flow channel pipe is narrowed toward an inner portion side of the valve main body from an outer portion side of the valve main body. The opening hole is formed by being punched toward an outer portion side from the inner portion side of the valve main body.
