Abstract
A passenger conveyor, such as an escalator or a moving walkway, in which a device for transmitting a change of direction of the movement of treadboards to a passenger by changing the passenger's sense of touch is provided in the vicinity of a boundary between a horizontal path and an inclined path. With this construction, a level difference between the adjacent treadboards is produced when the treadboard moves into the inclined path, thereby preventing the passenger from accidentally falling down.
