Provided is a governor for elevator which permits easy assembling adjustment work due to a simple construction, has a high degree of freedom in the arrangement of fly-weights, an overspeed switch and a rope grasping mechanism and the set mass of the fly-weights, enables the arrangement of the fly-weights and the like, the mass of the fly-weights and the like to be determined specifically for each of the first overspeed detection speed and the second overspeed detection speed, and can detect each of the first overspeed detection speed and the second overspeed detection speed with good accuracy. For this purpose, a governor for elevator which, in order to stop a car of an elevator, detects that the moving speed of the car has reached a first overspeed detection speed and a second overspeed detection speed, includes a first overspeed detection mechanism which detects that the moving speed of the car has reached the first overspeed detection speed, and a second overspeed detection mechanism which is provided separately from the first overspeed detection mechanism and detects that the moving speed of the car has reached the second overspeed detection speed. The first overspeed detection mechanism and the second overspeed detection mechanism are configured to work independently of each other.
