摘要

Is provided between the initial stop position of the balance weight 7 when the car 6 is stopped at the uppermost layer at the time of installation and the weight buffer 11 disposed below the balance weight 7, (30) mechanically contacting the balance weight (7) and giving a disturbance when the deterioration extension amount generated in the protrusion member (5) exceeds a preset allowable range, and the protrusion member (30) Has a cross-sectional shape that becomes a desired specific frequency defined so that the vibration transmitted to the car (6) through the balance weight (7) becomes smaller than a predetermined vibration frequency.;
