PROBLEM TO BE SOLVED: To provide a valve gear capable of being assembled more simply and accurately. SOLUTION: The device provides a valve body 110, a holder 120 mounting the valve body, an inserting member 23 for inserting the valve body and the holder, and a passage 22 communicating with the inserting member. In the valve gear in which the valve body opens and closes a port 22a of the passage, and the holder regulates amount of lift of the valve body simultaneously, the holder is provided with a valve mounting member 121 and a transforming member 122 integrally formed with the valve mounting member. The transforming member is fixed in pressure welding to the inserting member in such a manner that the transforming member, which is gradually transformed in shape, is made to be inserted into the inserting member. Further, a concave member 23b mounting a pin 130 is provided at the inserting member, and the holder is fixed at the pin in pressure welding. COPYRIGHT: (C)2004,JPO
