Summary:PURPOSE:To prevent wearing in a wheel of a cage door and a rail by setting up an engaging device in the intermediate between the cage door and a riding spot door and further a link-winding streak unit to a side of the engaging device frown the cage door. CONSTITUTION:A position, of a loop-shaped belt 8 for driving a cage door 1 of engaging a riding spot door 14 is placed in the vicinity of a position of an engaging device comprising an engaging piece 11 and engaging rollers 19, 27 provided between the cage door 1 and the riding spot door 14. When the cage door 1 is driven, its driving force, is transmitted to the riding spot door 14 through the engaging device, and now when the position of the loop-shaped belt 8 is placed adjacent to the position of the engaging device, angular moment about a vertical shaft, applied to the cage door 1, can be decreased to make it possible to decrease friction by contact between a rail 4 mounted to a cage door hanger case 5 and an edge part of a wheel 3 provided in a cage door hanger 2. In this way, wearing in the rail 4 and the wheel 3 of the cage door 1 can be suppressed.
