DEVICE FOR RESTRAINING THE RISE OF A STEP ROLLER OF AN ESCALATOR

摘要

A device for restraining the rise of a step roller of an escalator prevents the step roller from colliding with rails of a track in turn around areas at the top and bottom of the escalator. The device comprises: a supplementary roller, which is disposed between an outer rail and an inner rail of the track; an elastic member for biasing the supplementary roller toward the outer rail to roll thereon; and a supporting block to which the elastic member is fixed.
