Abstract
In a machine-room-less elevator, a hoisting machine is disposed directly above a counterweight. A counterweight speed governor is disposed higher than a position of the counterweight if a car descends to a floor portion of a hoistway and the counterweight jumps upward. When viewed from directly above, at least a portion of the counterweight speed governor is disposed at an identical position to a first counterweight guide rail in a width direction of the counterweight, and is disposed at an identical position to a portion of a suspending body between a driving sheave and a counterweight suspending sheave in a direction that is perpendicular to the width direction of the counterweight.
