Abstract

An electrically controlled throttle apparatus is constructed with a throttle body and a throttle valve that are simultaneously formed in the same dies. The throttle valve is rotatably assembled in a bore wall part of the throttle body while the throttle valve is rotated by a predetermined rotation angle θ with respect to a rotation angle 0° corresponding to its full close position. Besides, a clearance is formed between the throttle body and the throttle valve around a portion in the vicinity of a throttle shaft of the throttle valve and a shaft hole of the throttle body. Furthermore, a joint is inserted between the throttle shaft and the shaft hole in the forming process thereof. Thus, the throttle body and the throttle valve can be separated by the molding dies and the joint, and the throttle body and the throttle valve can be prevented from welding to each other in a forming process thereof.
