In a passenger conveyor, a supporting angle that is supported on a building beam is fixed to an end portion of a truss main body. A plurality of movement limiting members that come into contact with the supporting angle to limit horizontal movement of the supporting angle are disposed on the building beam. The supporting angle includes: a first supporting portion; and a pair of second supporting portions that are disposed on two sides of the first supporting portion in a width direction of the truss. A horizontal protruding dimension of the first supporting portion from the truss main body is different than horizontal protruding dimensions of the second supporting portions from the truss main body.
