Abstract
In a buffer device for an elevator, a hydraulic buffer that alleviates shock generated when a traveling body impacts at the bottom of a hoistway is located at the bottom of the hostway. Provided between the traveling body and the bottom of the hoistway is an elastic member that is elastically deformed and that alleviates the shock generated by the impact of the traveling body with the hydraulic buffer. The elastic member is arranged so that, when elastically deformed, almost fall of the elastic member is positioned within a range of a vertical dimension of the hydraulic buffer.
