As shown in fig. 1, the diameter of the outer handrail belt drive sprocket 8b is larger than the diameter of the inner handrail belt drive sprocket 8 a. Since the length of the outer handrail belt 10b is definitely longer than the length of the inner handrail belt 10a, the linear speeds of the outer handrail belt drive sprocket 8b and the inner handrail belt drive sprocket 8a are definitely different at the time of operation, but the outer handrail belt drive sprocket 8b and the inner handrail belt drive sprocket 8a are ensured to rotate at the same angular speed, so that the diameter of the outer handrail belt drive sprocket 8b is larger than the diameter of the inner handrail belt drive sprocket 8 a. The specific difference or ratio between the diameter of the outer handrail drive sprocket 8b and the diameter of the inner handrail drive sprocket 8a is determined mainly by the shape of the fan-shaped steps.
