<p>A structure in which an input shaft constituting a member for connecting a cylindrical switching valve and a rotary mechanism together, and the cylindrical switching valve are brought into contact with each other via a ball-like member. When this structure is employed, the ball-like member serves as a ball joint, so that rotation can be smoothly transmitted even when there is an angle of inclination between the direction of the axis of rotation of the input shaft by which the rotary mechanism for rotating the cylindrical switching valve and the same switching valve are connected, and the direction of the axis of rotation of this switching valve.</p> |
