BUSH FOR SUPPORTING DRIVE SHAFT IN POWER STEERING OIL PUMP

摘要

A bush for supporting a drive shaft of a power steering oil pump is provided to increase wear resistance and prevent partial wear and noise generation by forming a path groove easy to introduce working oil. A groove(21) easy to introduce working oil to an inner peripheral surface thereof are formed long in a bush(20) to connect upper and lower ends of the bush to each other, so that the working oil lubricates between the bush and a drive shaft when the drive shaft rotates.
