SOLUTION: A top plate sliding structure is constituted by providing first supporting member 13 arranged on the both left and right end side lower surfaces of the top plate 11, the second supporting members 14 arranged on the opposing upper part side surfaces of side plate 12 and a guide mechanism 15 arranged on the opposite surfaces of the first and the second supporting members 13 and 14. The guide mechanism 15 consists of rail members 24 arranged in the first supporting members 13 and holding members 25 which are arranged in the second supporting members 14 and also include plural bearings 33 and the rail members 24 and the holding members 25 are made to be mutually movable with the bearings 33. Door rollers are provided on this side upper surfaces of the second supporting members 14 so that the lower surface of the top plate 11 can be supported.</p> |
