PROBLEM TO BE SOLVED: To provide a passenger conveyor, facilitating adjustment of a drive sprocket and an anti-vibration rail by eliminating need of mechanical work to a back surface of a getting-on/off board beam for preventing it from getting in contact with a pallet. SOLUTION: A getting-on/off board 1 is supported from downward by the getting-on/off board beam 2. The pallet 3 is disposed under the getting-on/off board 1, and rollers 4 are provided on both side surfaces. The rollers 4 are connected by an endless chain 5 at a prescribed pitch. At one turning end part of the chain 5, the drive sprocket 6 is provided, and its outer circumferential part is engaged with the chain 5, so that it rotates to transmit drive force to the chain 5. The anti-vibration rail 7 is provided under the getting-on/off board 2, and it has a projection 7a to displace the moving locus of the roller 5 upward immediately before the drive sprocket 6. The projection 7a is disposed to be positioned ahead of the pallet 3 in the advance direction to the getting-on/off board beam 2. COPYRIGHT: (C)2006,JPO&NCIPI
