Abstract:
 To prevent oil from adhering to a brake disc when the oil leaks from a bearing unit. A first bearing unit (b1) of a motor (110) is disposed in a state of being inserted into a bearing unit insertion part (124) of a sheave (120), and is therefore positioned on the inner peripheral side of a rope winding part (122). The rope winding part (122) of the sheave (120) has a brake disc (D) formed integrally therewith on the motor side. In order to prevent oil from reaching the brake disc (D) when oil leaks out from the first bearing unit (b1), three systems of oil guide structures (210, 220, 230) for guiding leaked oil to a position set apart from the brake disc (D) are provided.
