An escalator step riser is improved by adding grooves to the cleat surfaces, and, at the same time, a skid- inhibiting function is realized at the rear edge of the step. For escalator step (1), cleats (5a) are formed with a pitch twice that of tread (4) on riser (3). On each cleat (5a) of the riser (3), one or more grooves (6) are formed in the longitudinal direction. In addition, skid- inhibiting surface (7), made of a synthetic resin and having a prescribed width, is attached in a quick connecting/disconnecting manner on the rear edge of step (2). A serrated irregular portion (7c) is formed on the upper surface of cleats (7a), (7b) of the non-slip surface (7).
