Claims

[Scope of utility model registration request]

A governor sheave, around which a governor rope linked to the elevator car or counterweight is wrapped, is attached to the bearing of the stand via a rotatably provided shaft, and a claw is attached to the arm of the governor sheave that rotates due to the centrifugal force accompanying this rotation. A flyweight is provided on the outer periphery of the bearing portion of the stand, and a ratchet is provided on the outer periphery of the bearing portion of the stand, which engages with the pawl and rotates when the flyweight rotates by more than a predetermined amount due to centrifugal force, and a rope protrudes from the ratchet toward the outer periphery. In an elevator governor equipped with a gripping and holding hook, the ratchet is composed of a boss portion, an arm portion, and an annular rim portion protruding from the outer periphery of the arm portion toward the governor sheave side, and 1. A speed governor for an elevator, characterized in that an inner circumferential surface thereof is provided with a tooth portion with which a pawl of the flyweight engages.
