きる。At this time, the guide groove 31 of the holding guide 30 and the sliding groove
Since the knob 36 is guided by the guide 32, the holding guide 30
The drop rod 37 rotates about the vertical axis in the inside, and it is possible to prevent the pick rod 36 and the holding guide part 30 from being entangled on both sides of the guide groove 31, and to prevent damage to the grip rod 36. Prevention and drop stick
37 can be raised smoothly. Further, a pressing member 41 is provided on the holding guide portion 30 side of the picking rod 36, and the pressing member 41 is urged toward the holding guide portion 30 side by the coil spring 42 to abut on the guide groove 31 side of the holding guide portion 30. Since the sliding is performed in the state in which the knob 43 is held, the finger or the like holding the knob 43 is not damaged by the guide groove 31, and the knob 36 can be safely pulled up.

に比較してその操作が非常に容易である。When the drop rod 37 rises to the raised position and the knob rod 36 corresponds to the engaging hole 33, the urging force of the coil spring 45 is greater than that of the coil spring 42. The rod 36 slides in the engaging direction, and the tip of the knob 36 engages with the engaging hole 33 in the holding guide part 30,
The drop bar 37 is locked so that it cannot drop at the raised position. Therefore, the drop bar 37 can be easily locked at the raised position by simply pulling up the pick bar 36, and the operation is much easier than in the related art that requires a rotating operation.

Can be covered with a cap 47, and compared with a case where only the upper end opening of the holding guide portion 30 is closed with a flat portion 48,
The appearance of the upper end side is good.

い。In the embodiment, the door main body 4 in which two sets of doors 5 and 6 are connected is exemplified, but the configuration of the door main body 4 side is not a particular problem. Also, in the case of adopting a door body 4 in which two sets of doors 5 and 6 are connected as in the embodiment,
The connecting member 9 may be provided with a holding guide portion 30 so that the connecting member 9 also serves as a guiding member. Alternatively, a guiding member may be provided separately from the connecting member 9. In addition, it goes without saying that various design changes can be made without departing from the spirit of the present invention.
