The invention discloses an elevator speed governor which comprises a plumb shaft used for driving the elevator speed governor to rotate. The speed detection mechanism is used for detecting the speed of the elevator car, the plumb shaft is sleeved with the speed detection mechanism, and the speed detection mechanism and the plumb shaft synchronously rotate; the spring stroke adjusting mechanism is connected to the plumb shaft in a sleeving manner and is arranged in the speed detection mechanism; the spring stroke adjusting mechanism is connected with the plumb shaft through a one-way bearing so that the spring stroke adjusting mechanism can rotate along with the main shaft only when the elevator descends. The speed limiter comprises a set of speed detection mechanism and a set of spring stroke adjusting mechanism, and the purposes of detecting the overspeed behavior during ascending and descending and stopping the lift car respectively when the ascending speed and the descending speed of the elevator are different can be achieved.
