It rotates in the opposite direction to the shaft.

At this time, since the end of the inner shaft is inserted into the operating hole of the lever, the lever is also moved in a straight line in the rotational direction of the inner shaft, that is, in the direction of the locking fixture, by the inner shaft being rotated, so that the door lock of the lever protrudes from the housing. By being inserted into the locking fixture, as shown in FIG. 11, the door is locked.

In addition, when the lever is linearly moved in the direction of the locking fixture, the second operating table provided in the cam actuator of the lever comes into contact with the other side of the rotating table, that is, the second contact portion of the rotating table, and pulls the rotating table in the moving direction of the lever. The cam is rotated (for example, in a clockwise direction) with respect to the center of rotation to linearly move the lock frame outward of the housing, thereby exposing the lock hole to the outside of the housing.

That is, when the lever moves in a straight line in the direction of the locking fixture, the working rod of the cam rotates (for example, clockwise) with respect to the center of rotation and moves along the cam connection hole of the lock frame (in the direction of lever movement), so the rotational movement of the cam This is transmitted to the lock frame and the lock frame is linearly moved outward of the housing, and the lock hole of the locking device is exposed to the outside by the linear movement of the lock frame.

That is, while the door is locked by the lever operation of the shaft centered on the pivoting body, the lock hole is exposed to the outside of the housing so that the lock can be fastened.
