The invention relates to the field of elevators, in particular to an anti-falling unit for an elevator and discloses an anti-falling unit of an elevator. The anti-falling unit of the elevator comprises a bracket fixedly connected with a lift car and a guide rail arranged along an elevator well. The anti-falling unit of the elevator is characterized by also comprising a first gear, a second gear, a roller wheel, a triggering unit, a connection rod, an elasticity restoring part and a support shaft, wherein the triggering unit is mounted on the bracket; the roller wheel and the first gear are mounted on the bracket through the support shaft in a manner of freely rotating; the guide rail is arranged between the first gear and the roller wheel; the first gear is meshed with the toothed surface of the guide rail; the roller wheel is in rolling fit with the smooth surface of the guide rail; the second gear revolves around the first gear through the connection rod; the second gear and the first gear are meshed with each other; a triggering hole in splicing fit with the triggering end of the triggering unit is formed in the connection rod. When the triggering end is withdrawn from the triggering hole, the second gear is meshed with the guide rail by means of the elastic action of the elasticity restoring part; the freedom degree of the mechanism is 0 at the moment, so that the elevator cannot run up and down, namely the falling prevention of the elevator can be implemented.
