To suppress abrasion and damaging of a gear by maintaining the lubricity of a tooth surface even when there is restriction on the consistency of usable grease.SOLUTION: This crane electrically-driven hoist has a reduction gear 40 that adjusts the rotational speed of a drum on which a wire rope for suspending a load is wound. The reduction gear 40 has a gear 42a that is rotatably supported and a fin 44a that is fixed to a gear shaft of the gear 42a. The fin 44a rotates along with rotation of the gear 42a, and supplies grease 43 present inside the reduction gear 40 to the tooth surface of the gear 42a.SELECTED DRAWING: Figure 3

    【課題】使用できるグリースのちょう度に制約がある場合でも、歯面の潤滑性を保持して歯車の磨耗及び損傷を抑制する。【解決手段】吊り荷を吊るためのワイヤロープが巻かれたドラムの回転速度を調整する減速機40を有するクレーンの電動巻上機である。減速機40は、回転自在に支持された歯車42aと、歯車42aの歯車軸に固定されたフィン44aとを有し、フィン44aは歯車42aが回転することで回転して減速機40の内部に存在するグリース43を歯車42aの歯面に供給する。【選択図】図3
