Therefore, the locking member 70 is composed of the stator 60.
Since the stator 60 is mounted integrally with the valve main body 51, the position of the locking member 70 relative to the valve main body 51 is determined on the valve main body 50 side in the rotational direction, and the axial line of the can is determined. In this case, the contact surface 59 prevents the stator 60 from coming off the can 52.

As a result, the positioning of the stator with respect to the valve main body 50 is facilitated, and the above-mentioned positioning is facilitated by forming the recess cross section in an arc shape, and the stator 60 is positioned on the valve main body. Easy to put on.
Moreover, since the positioning is easily performed in the rotating direction of the stator, and the elastic support is used, the relative position does not shift due to vibration or the like. It can be said that the mounting condition is particularly excellent because it will be automatically positioned at the center.
Therefore, after the stator 60 is pushed downward from above, the locking tool is set at a predetermined position of the concave groove, and its tip end is brought into contact with the contact surface to be locked, whereby the rotation and removal of the stator 60 are prevented. The stop will be blocked.
