The present invention relates to a vehicle alternator comprising: a rotary shaft shaft-inserted into a pulley; a nut coupled to one side of the rotary shaft in order to prevent the separation of the pulley from the rotary shaft; and a blocking part for covering and protecting the end portion of the rotary shaft exposed to the outside of the pulley along the axial direction of the rotary shaft. The present invention, unlike conventional technology, blocks, with a cap, the end portion of the rotary shaft exposed to the outside of the alternator to prevent corrosion and protect the rotary shaft, and can allow the cap to be separated from the nut without integrally fastening the cap and the nut, so as to facilitate a nut coupling operation. |
