７の係合が外れることになる。That is, as explained in FIG. 1, when the screw 33 is extended, the support frame 21 swings about the central axis 27 when viewed from the front, so the portion of the front frame 34 that is in contact with the protrusion 47 is , but the front frame 34 is rotated so as to be drawn inward whether it is rotated upward or downward. Therefore, the front frame 34 and the protrusion 47 do not come out of contact with each other due to rolling. However, if the height of the central axis 27 and the protrusion 47 is
7 is at a much lower position than the central axis 27, when the iij side frame 34 moves -1- due to rolling, it swings outward, and when it moves downward, it moves inward. Rotate, front frame 34 and protrusion 4
7 will be disengaged.

Since the support frame 21 swings around the central axis 27,
The part of the front frame 34 that is in contact with the protrusion 47 is at the same height as the central axis 27, so it moves downward in an arc, but the front frame 34 does not rotate upward or downward. In any case, it rotates so as to pull it inward. Therefore, the front frame 34 and the protrusion 47 do not come out of contact with each other due to rolling.
