Reference numeral 81 is a fixed engagement roller that is axially attached to the door hanger 43. The same reference numerals as those in FIGS. 6 and 7 denote the same components. Further, in the present embodiment, the engagement plate 6 is taken into consideration due to the arrangement of the car side door opening / closing drive device and the like.
Since 1, 62 and the like are located slightly below the door hanger 25, the car-side door 13 is made longer than the landing-side door 14 so that the engagement rollers 80, 81 of the door hanger 25 can be opened and closed when the door is opened and closed. The engagement plates 61 and 62 are engaged at a slightly lower position.

Next, the operation of this embodiment will be described.
In the state where the door is closed, the roller 73 is in contact with the stopper 74 as shown in FIG. In this state, since the gap g is kept between the movable engagement roller 80 and the fixed engagement plate 61, and between the fixed engagement roller 81 and the movable engagement plate 62, the car 4 smoothly passes through the landing, You can also stop landing at the landing.

The car 4 stops landing at the landing and the car door 1

As described above, the car door 13 and the landing door 14 are opened together with the engagement rollers 80 and 81 sandwiched by the engagement plates 61 and 62 from both sides. The opposite is true when closing. Since the parallel links 63 and 64 are substantially perpendicular to the longitudinal direction of the movable engaging plate 62 when the movable engaging plate 62 descends, the parallel links 63 and 64 are not moved from the landing door 14 via the fixed engaging roller 81 during the door closing operation. Even if a force is applied, the movable engaging plate 62
Does not rock.

As described above, according to this embodiment, the engaging rollers 80 and 81 are sandwiched by the engaging plates 61 and 62 from both sides, and the parallel links 63 and 64 are substantially perpendicular to the longitudinal direction of the movable engaging plate 62. Therefore, since the movable engaging plate 62 is prevented from swinging, a smooth door opening / closing operation can be performed. In the above description, when the door is opened, the movable engaging plate 62 is lowered by its own weight, but a spring may be used to forcibly lower the movable engaging plate 62.

In the above embodiment, the guide guide 65 is shaped so as to surround the roller 72, but any shape may be used as long as the roller 72 can push up the movable engaging plate 62. Further, although the engagement plates 61, 62 and the like are located slightly below the door hanger 25 because of the arrangement of the car side door opening / closing drive device, etc., the engagement plates 61, 62, etc. are possible if possible due to the structure of the door. May be installed near the door hanger 25, and the landing door 14 and the car door 13 may have the same length.
