You can instantly determine which of the opening and closing operations is being performed,
It is easy to check the opening and closing of the valve shutter,
At this time, the valve shutter is not in the half-opened state, so that no abnormal noise is generated when the air conditioning is activated. Moreover, since the operating portion is a push button type pressing operating portion, it is sufficient if the hole is small as compared with the conventional dial type operating portion and simply has a size through which the pressing operating portion is inserted. It does not spoil the exterior of the vehicle interior. In particular, in the present invention, since the opening / closing operation mechanism of the valve shutter is all assembled into a unit to be a unit, even when the unit is assembled to the air conditioning blower, the unit is simply attached to a predetermined portion of the ventilator body. It only needs to be fixed, the workability is significantly improved and the production efficiency is also improved.

Further, when the operating member is composed of two members, and the first operating member connected to the crank and the second operating member forming the pressing operating portion are connected at a predetermined angle,
By pressing the pressing operation portion of the second operation member, the first operation member is moved obliquely at a predetermined angle. Therefore, a slight operation amount of the second operation member causes a predetermined rotation amount of the valve shutter. Can be obtained.
