The invention relates to an escalator step having an anti-chucking function. The escalator step having the anti-chucking function comprise a step body, a supporting plate, a pedal, a first spring, left and right anti-chucking mechanisms and a front and back anti-chucking mechanism. The escalator step having the anti-chucking function is ingenious in design, high in feasibility, capable of preventing clothes from being chucked at the left and right sides of the step body and also capable of preventing the clothes from being chucked between adjacent step bodies. When a person treads on the pedal of the step body, the left and right sides of the step body can be bounded by baffles so as to prevent the clothes from being chucked between the step body and skirt guard panels; a safety plate is also arranged between each two adjacent comb teeth of the front end face of the step body, and perfect engagement of two adjacent step bodies can be realized.
