Since the cylindrical wall 39, that is, the bypass valve holder 10, serves as a support member that supports the end of the guide tube 42 of the throttle wire 41, the number of parts and the number of assembly steps are reduced. Reduction can be achieved.
- the present invention is not limited thereto, and various design changes can be made without departing from the scope of the present invention.
