Description

  The present invention relates to a method for manufacturing a passenger conveyor tread plate that is connected endlessly and conveys passengers and the like.

In general, a passenger conveyor tread has a horizontally disposed cleat body, a riser body having a convex curved surface portion and a lower end portion connected to a rear end portion and an upper end portion of the cleat body, and a substantially triangular cross-sectional shape. And a bracket body that supports the cleat body and the riser body at both ends in the width direction. Conventionally, each part is joined by forming a screw hole at a predetermined position. At the same time, a bolt is screwed into the screw hole (see, for example, Patent Document 1).
