A1

[Problem] The present invention addresses the problem of providing the following: a hoist whereby noise and vibration produced while said hoist is operating are reduced without making said hoist more difficult to assemble; and a dynamo-electric machine provided with said hoist. [Solution] A hoist (M1) is provided with a rotating shaft (19) and a spider (18). A sheave (7) is affixed to the rotating shaft (19) around the axis thereof, and the rotating shaft (19) is supported by bearings (4, 5). The spider (18) is attached to a front-end section (19f) of the rotating shaft (19). A front-end-section periphery part (19e) for attaching the spider (18) and a protrusion (19t) for attaching the spider (18) are formed on the aforementioned front-end section (19f). Said protrusion (19t) extends axially from the front-end side of the rotating shaft (19). An attachment part (18f) that attaches to the outside of the aforementioned protrusion (19t) on the rotating-shaft side is formed in the spider (18), as is a rear-end-side extended part (18b) that attaches to the aforementioned front-end-section periphery part (19e).
