The invention discloses a rotary anti-deviation device for a handrail belt of an escalator. The anti-deviation device comprises an angular part, a fixed shaft, a guide block and a protective cover, the angular piece is arranged on the middle skirt panel; the fixed shaft is arranged on the angular piece; the guide block comprises a matching part and a rotary connecting part; the matching part is provided with an installation position located in an inner cavity of the handrail belt and a peripheral face matched with the inner cavity of the handrail belt at the installation position. The rotary connecting part is arranged on the fixed shaft and can rotate around the central axis of the fixed shaft; at the mounting position, the rotary connecting part is connected with the matching part through the notch of the hand strap; the protective cover is arranged on the fixing shaft and located on one side of the guide block. The protective cover faces the notch of the hand strap and at least covers a crack area formed between the notch of the hand strap and the rotary connecting part. The anti-deviation device is convenient to install and debug, can effectively prevent the hand strap from deviating during operation, and is high in practicability.
