PURPOSE:To facilitate positioning of a handle for rotation by mounting a projection on the inner peripheral surface of a temperature control handle to bring a ring into spline engagement with a main body and fitting the handle to the main body in such a manner that the handle is rotated, but not moved axially. CONSTITUTION:A projection 34 is mounted on the inner peripheral surface of a temperature control handle 16, and a ring 29 provided with a stopper portion 31 corresponding to the projection 34 is brought into spline engagement with a main body A. The handle 16 is fitted to the main body A in such a manner that the handle is rotated, but not moved axially. Thus, the rotation regulating position of the handle 16 can be easily adjusted to any position by contact of the projection 34 with the stopper portion 31. |
