PURPOSE:To enable the closing motion of a door to be smoothly effected with the provision of durability by configurating a device in such a way that the door is supported by both a front and a rear support arm while the closing motion of the door is being affected, meanwhile, the door is rotated and slided by means of both a front positioning and a rear positioning arm. CONSTITUTION:In order to open a door 4 from its closed position, the door 4 is pulled out of outside. This causes a front support arm 3a which supports the door 4, to rotate outward allowing both a front positioning arm 6 and a rear positioning arm 7 to rotate outward simultaneously. Then, these arms are suspended when they rotate by 90 deg. where the front arm 6 strikes its front end against a step of a bracket 2. Simultaneously, a projection 10 at the tip end of a lever 9 which is an integral part of the rear arm, 7, is displaced from a swing guide groove 16 of a stopper section 14 arranged on a rail 13 of the door 4 to a guide groove 15 accompanied with the rotation of the rear arm 7. Under this condition, the door 4 is pushed afterward through the rail 13 which engages with a roller 27 on the bracket 8, and the door 4 is opened.
