Abstract
A passenger conveyor guide arrangement comprises a guide rail which supports and guides step rollers mounted on the conveyor steps and a fastener which includes a nut and a bolt having a threaded shank and a substantially rectangular head for fastening the guide rail to the conveyor main frame. The guide rail includes a bottom guide portion for guiding a step roller tread and side guide portions vertically rising from the side edges of the bottom portion for guiding the roller sides. The bottom and the side guide portions together form a substantially U-shaped cross section. A side plate extends from the side guide portion at each side edge of the bottom guide portion in a direction substantially perpendicular to the bottom guide portion, and inturned portions extend from the lower end of the side plates in a direction substantially parallel to the bottom guide portion and each other to form a slit between the inner edges so as to engage the rectangular head of the bolt of the fastener.
