Abstract (en)
The present invention relates to a pump rotor of a vacuum pump for a vehicle capable of decreasing a friction force between a pump housing and a pump vane, and a pump rotor and enhancing durability in such a manner that a lubricant supply structure of a pump rotor is enhanced. In a vacuum pump that includes a shaft, a pump rotor that has a shaft hole, a plurality of vanes that are assembled to a vane sliding groove of the pump rotor, and a pump housing, there is provided a pump rotor comprising a concave groove part that is formed in a lateral surface of the pump rotor and is not connected with the vane sliding groove but is connected with the shaft hole for thereby forming an oil storing part therein.
