A speed governing system, a releaser, an elevator speed governing system, and an elevator. The speed governing system comprises a speed governor for detecting an overspeed condition of a motion device, and a releaser connected to the speed governor. The releaser comprises: a housing; at least one positioning pin having a section that is disposed in the housing and at least partially constructed to have an arc-shaped outline; and a releasing component passing through the housing and provided with a groove on its portion located in the housing, wherein the groove is constructed to be adaptable to the arc-shaped outline, for accommodating the section to fix the releasing component relative to the housing, and be separated from the section when the speed governor detects the overspeed condition and moves the releasing component relative to the housing.
