2)の降下速度を好適な速度に調節することができる。First, an evacuee climbs onto the board (6) of the power-free descent device of the present invention through a window of a building, operates the control lever (26), and locks the locking rod (25) into the locking body (not shown). When removed from the board, the weight of the evacuee is added to the boarding equipment (2), and the boarding equipment (2) side becomes a heavy object (15) moving up and down inside the square pipe (3).
), and the boarding and alighting equipment that evacuees were transferred to (2)
begins to fall. In this case, the descending speed of the getting on/off equipment (2) is adjusted to a suitable speed by using pinions (11) (16) with an appropriate number of teeth. When the descent speed of the boarding and alighting facility (2) becomes too fast due to the number of evacuees who have transferred to the boarding and alighting facility (2), the rotation control means (19) provided on the hanging body (5) of the boarding and alighting facility (2) By controlling the rotation of the axle (12) of the pinion (11), the boarding equipment (
2) The descending speed can be adjusted to a suitable speed.
