To provide an elevator hoist which discharges lubricating oil out of the hoist without allowing the lubricating oil to reach an encoder even when a lubricant leaks from an oil sealing material on a sheave side, and an elevator.SOLUTION: This hoist is provided with: a disk-shaped bearing cover 15 that is fixed to a bearing housing 9; a support shaft 16 that is provided on the rotational center axis of the bearing cover 15 so as to support an encoder 17 disposed inside a hollow part of a hollow main spindle; and an encoder support part that has a cylindrical support base 40 for holding the support shaft 16. An oil cut groove 22 for blocking movement of lubricating oil leaked from an oil sealing material 13 to the encoder 17 by radially dispersing the lubricating oil is provided to the outer peripheral part of the support base 40 of the encoder support part.SELECTED DRAWING: Figure 3

    【課題】綱車側の油密封材から潤滑剤が漏れた場合であっても、潤滑油をエンコーダに到達させることなく巻上機の外部へと排出するエレベーター用巻上機およびエレベーターを提供する。【解決手段】巻上機は、軸受ハウジング9に固定された円板状の軸受カバー15と、軸受カバー15の回転中心軸上に設けられた、中空状主軸の中空部内に配置したエンコーダ17を支持する支持軸16と、支持軸16を保持する円筒状の支持台40を有するエンコーダ支持部と、を備え、エンコーダ支持部の支持台40の外周部に、油密封材13からの漏れた潤滑油を放射状に飛散させてエンコーダ17へ移動することを阻止する油切り溝部22を設けた。【選択図】図3
