PROBLEM TO BE SOLVED: To close a landing opening part without a clearance even in the case of a landing opening wall extended from an elevating path by fitting a support for supporting a bar-like member of a curing sheet to the landing opening side wall, and forming the support by a fitting part, a closing part and a support part. SOLUTION: In this apparatus, plural bar-like members 3a-3d are installed horizontally at designated spaces in the direction of height in a curing sheet 2 of such a size as to enough cover a landing opening part 1. A first support 4 for supporting each one end of an arbitrary number of bar-like members 3a-3d is fixed to one side wall 6 formed to be extended from the inside of an elevating path. Second supports 5a-5c for supporting each one end on the opposite side of the bar-like members 3a-3c are fixed to a front wall 7 near the landing opening part 1. The first support 4 includes a fitting part fitted to the wall 6, a blockind part disposed to block up a clearance between the wall 6 and the curing sheet 2, and a support part having a cutout for supporting each one end of the bar-like members 3a-3c.
