However, this work is done by rotating the rotary seat around the suspension shaft, aligning the pin integrated with the rotary seat and the lock hole formed in the plate, and then moving the rotary seat to the suspension shaft. It is necessary to insert the pin into the lock hole by pushing it down in the axial direction. However, the alignment of the pin and the lock hole must be performed while looking through the slight gap between the lower end of the guide rail and the upper end of the suspension door from the side, and it cannot be performed easily as seen from above, so workability is improved. There are bad drawbacks.

  Moreover, the thing of patent document 2 engages with the engaging part of the fixed frame attached to the upper end surface of the suspension door by pressing and sliding the engagement body attached to the lower end of the suspension shaft of the door pulley in the door opening and closing direction. However, it is necessary to press and slide the door pulley in the opening / closing direction of the door through a slight gap between the guide rail and the upper end surface of the suspension door. If the engaging body is engaged with the engaging portion of the fixed frame, it is very difficult to disengage the engagement. Therefore, the height of the suspension door is determined at the first time, and the subsequent suspension doors. There is a disadvantage that fine adjustment of the height cannot be easily performed.
