The invention discloses an elevator speed governor which comprises a main shaft, the speed limiting mechanism is arranged on the main shaft, and the speed limiting mechanism and the main shaft are arranged in a synchronous rotation mode; the one-way rotating mechanism is mounted on the main shaft in a one-way rotating manner; the at least one first heavy block is mounted on the one-way rotating mechanism; the speed limiting mechanism at least comprises a linkage assembly, a speed limiting assembly and a second heavy block, the linkage assembly is arranged on the main shaft, the second heavy block is arranged on the linkage assembly in a swinging mode, the first heavy block abuts against the outer side of the second heavy block in an operable mode, and the speed limiting assembly is connected with the linkage assembly. Through the application of the elevator speed governor structure, when the ascending speed and the descending speed of an elevator are different, the ascending and descending overspeed behaviors can be detected, and the elevator car is stopped.
