５）を摺動自在に緊張して巻回している。(Prior Art) Figure 4 shows a conventional handrail drive device for a passenger conveyor. In the figure, (1) is the main frame of an escalator that is a passenger conveyor, and this main frame (1) It is equipped with a large number of steps (3) that circulate and move while being guided by an endless step rail based on the drive of the drive machine (2) of (IA), and parapets (4) are erected on both sides of the steps. This parapet (4) is equipped with an endless moving handrail made of rubber or the like and having a C-shaped cross section.

上部ローラ（７）と下部ローラ（８）が回転して移動手
摺（５）を摩擦力により循環移動させる。(6) is a handrail drive device disposed on the main frame (1), and this handrail drive device (6) has a plurality of upper rollers (7) rotatably pressed against the lower surface of the return side of the movable handrail (5). , a plurality of lower rollers (8) which are press-contacted to the return side surface of the moving handrail (5) so as to be able to follow and rotate, a sprocket (9) that rotates based on the drive of the drive machine (2), and this sprocket (9). )
and an endless chain (l) wrapped around the upper roller (7).
Therefore, when the drive machine (2) is driven, the sprocket (9) rotates and the chain (10
) are circulated, and the upper roller (7) and lower roller (8) that sandwich the return side of the movable handrail (5) rotate, and the movable handrail (5) is circulated by frictional force.

本体の構造に影響が生じる虞れがある。However, in the case of a high-lift escalator, the sliding resistance on the outgoing side of the moving handrail (5) is large, and in order to circulate the moving handrail (5) only on the return side, the strength of the moving handrail (5) must be significantly increased. We have to improve and there is a problem. That is, in order to improve the strength of the movable handrail (5), the movable handrail (5)
It is possible to improve the strength of the steel belt embedded inside the movable handrail (5), but if the thickness of the movable handrail (5) increases,
Since the bending rigidity of the moving handrail (5) becomes strong, if the bending radius of the moving handrail (5) is not increased, fatigue failure may easily occur, which may affect the structure of the main body of the escalator.
