PROBLEM TO BE SOLVED: To provide structure of a throttle valve device 1 capable of maintaining concentricity through an intermediate shaft 13, an output shaft of an actuator and a valve stem of the throttle valve by reducing stress generated when connecting the intermediate shaft 13 to a body 5. SOLUTION: A fitting hole 20 for fitting the intermediate shaft 13 and a void 24 for exposing an outer peripheral surface of the fitted intermediate shaft 13 is arranged in a connecting part 21 connected to the intermediate shaft 13. Thus, the stress generated when connecting the intermediate shaft 13 to the body 5 can be reduced by releasing to the void 24. Thus, reduction in holding power of the intermediate shaft 13 by the connecting part 21 can be prevented by reducing risk of causing resin cracks and creeps by the stress. As a result, the concentricity through the intermediate shaft 13, the output shaft of the actuator and the valve stem of the throttle valve can be maintained. COPYRIGHT: (C)2007,JPO&INPIT
