ELEVATOR GOVERNOR

PROBLEM TO BE SOLVED: To provide an elevator governor miniaturized, having excellent installability, and certainly detecting the actual lifting/lowering speed of an elevating/lowering body. SOLUTION: This governor includes: a sheave 15a with rotational speed in one direction changed in response to the lifting speed of the elevating/lowering body and rotational speed in the other direction changed in response to the lowering speed of the elevating/lowering body; a first speed governing mechanism body 20 provided to the sheave 15a and composed of flyweights 28, 29 detecting lifting overspeed when the elevating/lowering body lifts by changing a turning rate in response to the rotational speed of the sheave 15a in the one direction; and a second speed governing mechanism body 21 provided to the sheave 15a separately from the first speed governing mechanism body 20 and composed of a flyweight detecting lowering overspeed when the elevating/lowering body lowers by changing the rotational rate in response to the rotational speed of the sheave 15a in the other direction.
