An example of rotating the ventilation fan C (turning around the pivot 5 as a fulcrum) via the wire 17 having the above configuration will be described (however, this is an operation after releasing the lock 20 described later). Pulling down and pulling one of the wires 17 in the direction of the arrow “I” causes the rotating cam 10 to rotate in the clockwise direction (in the direction of the arrow “B”) via the locking ring 11. With this rotation, the other end of the wire 17 is pulled in the direction of the arrow “I-1”, and the pivot 5 is rotated in the clockwise direction. That is, the ventilation fan C rotates in the clockwise direction. By sequentially proceeding with this operation, the state rotates from the state shown in FIG. 4A to the state shown in FIG. As described above, the ventilation fan C can be changed from the suction state to the exhaust state. Note that one and the other of the wires 17 are in the vertical position (the pulley 15
a), 15b, 15c, and 15d, or brackets 13a, 13b, 13c, and 13d (positions) are different from each other, and the structure is not entangled.

In order to change from the above-described state (from the exhaust state to the suction state), after releasing the lock 20 again, the grip rod 18 is pulled down and the other end of the wire 17 is moved in the direction of the arrow “C”. When pulled, the rotating cam 10 rotates in the counterclockwise direction (in the arrow “d” direction) via the locking ring 11. With this turning, one of the wires 17 is pulled in the direction of the arrow “C-1”, and the pivot 5 turns in the counterclockwise direction. That is, the ventilation fan C rotates in the counterclockwise direction. By sequentially proceeding with this operation, the state rotates from the state of FIG. 4-2 to the state of FIG. 4-1. As described above, the ventilation fan C can be changed from the exhaust state to the suction state. Note that this return (change from the exhaust state to the suction state) may be performed by compressing and rubbing a spring (not shown) instead of the wire 17. Furthermore, this wire 17
And a spring can be used together. And although the location which provides this spring has the axis | shaft 5, the rotation cam 10, etc., the location is not limited.

Next, the mechanism of the lock 20 will be described. The lock 20 is a first lower frame portion 2 of the frame body 2.

1b), the locking of the lock pin 22 and the back surface 401a of the second lower frame 401 is released. By rotating the ventilation fan C through this opening, the ventilation fan C can be changed from the exhaust state to the suction state. After the change, when the pull of the wire 17 with respect to the roller 23 is released, the position of the lock pin 22 is restored by the reaction force of the spring 25, and the inclined surface of the lock plate 26 is pushed up to be in the initial locked state. A structure in which the unlocked state is replaced by an automatic lock mechanism (automatic stop mechanism) (not shown), or a lock mechanism (automatic control mechanism) for automatic control is also possible.
