PURPOSE:To make inexpensive an operating devcie for opening and closing a movable wall and facilitate the operation of the device by a method wherein an extension arm extended from a side wall constituting a movable wall capable of moving upwards is supported by a lift guide arm connected to a rear wall part of a vehicle and a lifting piston. CONSTITUTION:Side wall 2, 3, 4 parts are pivotably connected to front wall, floor 5, rear wall 6 parts to constitute the movable wall. The extension arm 7 extended in parallel on the surface of the pivotably connected side wall 3 of the movable wall is supported by the lift guide arm 8 and the piston 9 between a right-side rotation center line 12 and a connecting point of the arm 8, and the arm 8 and the piston 9 are connected to parts 14, 15 of the rear wall 6, repectively. The same applies to the front wall at a front part. The movable wall is opened and closed by operating the piston 9. An auxiliary arm 10 is extendd in parallel to the guide arm 8, an auxiliary rope 18 is attached to the arm 10, and a force is exerted to the movable wall through the rope 18 at the time of fully opening the wall. Further, an auxilary rope 19 is attached to a lower end part of the side wall 3, and a force is exerted on the movable wall through the rope 19 at the time of fully closing the wall. |
