PROBLEM TO BE SOLVED: To provide a work time safety ensuring device and the like for an elevator in which a worker can recognize the presence or absence of an alarm more surely, irrespective of the presence or absence of noise, an orientation direction of the worker, and a working position of the worker.SOLUTION: A work time safety ensuring device 21 for an elevator includes: an alarm control unit 23; a car position detection unit 25 for detecting a position of a car 5 in a hoistway 3; a balance weight position detection unit 27 for detecting a position of a balance weight 7 in the hoistway; and at least one portable vibrator 29. The portable vibrator vibrates due to the existence of an alarm output command by radio from the alarm control unit. The alarm control unit transmits an alarm output command to the portable vibrator, on the basis of the detection result of the car position detection unit and the balance weight position detection unit, at least one of when the balance weight approaches an upper part of the car or when the balance weight approaches a pit of the hoistway. |
