To prevent damage to a rechargeable electric driver when an ascender is stopped from operating.SOLUTION: An ascender 100A includes differential reduction type deceleration means that has an input shaft 1A capable of being driven by a rechargeable electric driver and an output shaft connected to a pulley around which a rope can be wound, and reduces the forward rotation applied to the input shaft 1A and transmits it to the output shaft. The ascender also includes: a one-way clutch unit 401 that is attached to the input shaft 1A and allows the input shaft 1A to rotate forward and restricts the reverse rotation; and a rotation restriction/release unit 402 that restricts or releases the rotation of the one-way clutch unit 401 around an axis of the input shaft 1A. Ascending is performed by making the rotation of the one-way clutch unit 401 into a restricted state and driving the input shaft in the forward direction in a climbing direction using the rechargeable electric driver, and descending is performed by releasing the rotation restriction of the one-way clutch unit 401 and allowing the pulley and the deceleration means to rotate in the reverse direction using the tension generated in an entrance side rope on which the user's weight is applied.SELECTED DRAWING: Figure 10

    【課題】登高器に対する稼働停止時の充電式電動ドライバの損壊を防止する。【解決手段】充電式電動ドライバにより駆動可能な入力軸1Aと、ロープを巻き掛け可能なプーリと結合された出力軸を有し、入力軸1Aに加えられた正回転を減速して出力軸に伝達する差動減速式の減速手段を備えた登高器100Aであって、入力軸1Aに装着されて、入力軸1Aの正回転を許容し、逆回転を制限するためのワンウエイクラッチ部401と、入力軸1Aの軸周りへのワンウエイクラッチ部401の回転を拘束したり、解除したりする回転拘束・解除部402とを備えた。登高は、ワンウエイクラッチ部401の回転を拘束した状態にして、充電式電動ドライバにより入力軸を登高方向へ正回転駆動することで行い、下降は、ワンウエイクラッチ部401の回転拘束を解除し、ユーザの体重が掛かった入り口側ロープに生じる張力によりプーリと減速手段を逆回転可能にすることで行う。【選択図】図10
