PURPOSE:To prevent the contact of a door with a side wall of a car by having such a construction as a slide mechanism does not operate unless the movement in the corbel direction of the door by a link mechanism is completed or the link mechanism does not operate during the movement of the door. CONSTITUTION:When a door 3 makes open opeation, an open and close cylinder 9 and an in and out sylinder 14 are operated to project each of piston rods 9a and 14a. After that, the door 3 and second guide mechanism 5 are guided by the first guide mechanism 4, and they are corbeled in the direction of (a). Then, when the piston rod 14a reaches the moving end of the corbel direction, a roller plunger 31a of a limit valve 31 is pushed and reduced by a limit plate 32. When the door 3 is moved in the corbel direction by a specific size, the piston rod 9a is only projected. In addition, a sliding piece 5b of the second guide mechanism 5 and a coupling metal fixture 8 are moved in the (c) direction as an open direction along a guide rail 5a and, at the same time, the door 3 is moved in the (c) direction. |
