An escalator avoids jamming by preventing the edges of coins 5 from colliding with a path plate 4 in a curved portion 2 of the escalator, and prevents the deformation of the escalator by increasing the strength of the curved portion. The path plate, at the curved portion of the escalator, has a strengthening recess or trough 6 that extends along the direction in which coins pass, such that the upper ends of coins passing through the curved portion do not collide with the path plate.
