1. A pulley for an alternator, comprising:
an outer wheel, provided with an axle hole at the center; a clutch wheel, fixedly disposed in the axle hole of the outer wheel and having a pivot hole; a hollow connecting shaft, having a first end and a second end, wherein the first end is rotatably disposed in the pivot hole of the clutch wheel so that the hollow connecting shaft maintains a co-rotational relationship with the outer wheel in a first relative rotation direction by means of the clutch wheel, while in a second relative rotation direction, the hollow connecting shaft is disassociated from the co-rotational relationship with the outer wheel and presents an idling state; and the second end of the hollow connecting shaft is provided with a first protruding portion; a hollow core shaft, having a first end and a second end, wherein the hollow core shaft is rotatably received in the outer wheel, and the second end of the hollow core shaft is rotatably arranged at the second end of the hollow connecting shaft; the second end of the hollow core shaft provided with a second protruding portion, and the second protruding portion corresponds to the first protruding portion; and an elastic element, disposed between the second end of the hollow connecting shaft and the second end of the hollow core shaft. |
