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 ( 5 a) are formed with a pitch twice that of tread ( 4 ) on riser ( 3 ). On each cleat ( 5 a) of the riser ( 3 ), one or more grooves ( 6 ) are formed in the longitudinal direction. In addition, skid-inhibiting surface ( 7 ), made of 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 ( 7 c) is formed on the upper surface of cleats ( 7 a), ( 7 b) of the non-slip surface ( 7 ).
