<P>PROBLEM TO BE SOLVED: To provide a valve unit 1 capable of improving positional accuracy of a valve 5. <P>SOLUTION: This valve unit 1 includes: a valve 5 disposed inside a valve housing 3 and supported by a shaft 4; and a stopper means regulating a fully opened position and a fully closed position of the valve 5. The stopper means comprises a stopper part 11 rotated integrally with the valve 5 and a stopper receiving part 12a disposed opposite the stopper part 11 in the rotation direction of the stopper part. The stopper part 11 is integrally formed of the same material as the valve 5, regulates the fully closed position of the valve 5 by abutting against the stopper receiving part 12a at a valve-closing side when the valve 5 is rotated in a direction for closing a valve passage 6, and regulates the fully opened position of the valve 5 by abutting against the stopper receiving part at a valve-opening side when the valve 5 is rotated in a direction for opening the valve passage 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
