Abstract
A passenger conveyor including body frame is formed of a main frame including upper and lower horizontal sections and an inclined section therebetween, and upper and lower auxiliary frames mounted on the upper and lower horizontal sections of the main frame, respectively. A front side of the upper auxiliary frame and the upper horizontal section forms a recessed portion, and a driving device for driving handrail is provided in the recessed portion so that the handrail driving device is positioned over the surface of the upper horizontal section and the width of the passenger conveyor is reduced without changing the height of the handrail driving device. The lower auxiliary frame and the inclined section of the main frame also form a recessed portion and a tension device is disposed in the recessed portion so as to be disposed over the main frame, whereby the passenger conveyor is reduced in width by 100-150 mm.
