第3738612号明細書及び実開昭61−36047号公報に
おいて公知である。Conventional Technology Conventionally, in gymnasiums and the like, in order to use the inside of the building for multiple purposes, telescopic movable bleachers are known, which are installed in a retracted state at one corner of a side wall when not in use, and extend to form a bleacher seat when in use. Further, a drive device for telescopically moving the telescopic seats is also known in US Pat. No. 3,738,612 and Japanese Utility Model Application No. 61-36047.

る構成のものである。 This known drive device comprises a number of single pieces, each consisting of a rotating drum in the form of a regular polygon, with rollers attached to the outer periphery of the drum in downward U-shaped channels whose length is approximately equal to the length of one side of said rotating drum. A single chain rail connected like a rail by a hinge is wound in a spiral shape, and the rotating drum is rotated by a motor to extend the chain rail,
The movable spectator seat attached to the tip of the chain rail is moved forward and backward on the floor by rolling it up.

らないことなどの欠陥があつた。Problems to be Solved by the Invention By the way, according to the above-mentioned drive device, by always keeping the extension angle of the chain rail constant as the rotating drum rotates, the tip of the chain rail can be made perpendicular to the axis of the rotating drum. Therefore, the rollers rolling on the floor and the axes of the hinges that connect the single pieces each have a feeding angle with respect to the direction perpendicular to the longitudinal direction of the single pieces. Such a mounting, especially for a single piece of rotating roller, is inconvenient in manufacturing, as it is placed in a correspondingly inclined position, and also causes a tortuous movement, and the chain rail is is derived obliquely corresponding to the feeding angle, so an invalid component occurs in the extrusion force,
It requires a large driving force and is unreasonable, since the rollers provided on each single piece will all roll at different positions on the floor surface.
There were deficiencies such as the need to maintain the levelness of the floor structure over a wide range.
