To provide a hoist capable of stably fixing a shaft and a rotor and achieving downsizing and low cost of a fastened part of the shaft and the rotor.SOLUTION: A boss part 11 of a rotor 6 of a hoist 1 has: a cylindrical body into which one end of a shaft 3 is inserted; and a flange 11b that projects to an inner circumferential side of the cylindrical body and faces an end surface of the shaft 3 on one end side. The flange 11b and one end of the shaft 3 are bonded via a taper pin 22 axially fitted through the flange 11b to the shaft 3. The taper pin 22 is prevented from being coming out from a rear end side by a pressing member fixed to the flange 11b. The pressing member has: a fixed part fastened to the flange 11b by a bolt at a position misaligned from the pin in the axial direction; a plate-like extension part having a base end side connected to the fixed part and extending in the axial direction and an intersecting direction; and a pressing part connected to a tip side of the extension part and brought into contact with the rear end side of the pin.SELECTED DRAWING: Figure 1

    【課題】シャフトと回転子をより安定して固定でき、シャフトと回転子の締結部の小型化や低コスト化を図ることができる巻上機を提供する。【解決手段】巻上機1の回転子6のボス部11は、シャフト3の一端が挿入される筒状本体と、筒状本体の内周側に突出し、シャフト3の一端側の端面に臨むフランジ部11bとを有する。フランジ部11bとシャフト3の一端は、フランジ部11bを挿通してシャフト3に対して軸方向に嵌入されたテーパピン22を介して嵌着される。テーパピン22は、フランジ部11bに固定された押さえ部材で後端側から抜け止めされる。押さえ部材は、軸方向においてピンからずれた位置でフランジ部11bにボルトで締結される固定部と、基端側が固定部に接続され、軸方向と交差方向に延びる板状の延在部と、延在部の先端側に接続されるとともにピンの後端側と当接する押さえ部と、を有する。【選択図】図1
