<P>PROBLEM TO BE SOLVED: To provide an oil supply device that can efficiently supply oil by preventing oil leakage. <P>SOLUTION: In the oil supply device 1 for supplying oil introduced into an oil flow path 2 to a supply destination, including: the oil flow path 2 disposed in a rotating shaft 3 held rotatably, and into which oil is introduced; and a guide member 4 provided along an inner peripheral surface 2b of the oil flow path 2 from a shaft end surface 3a of the rotating shaft 3, and for guiding oil from an oil source to the oil flow path 2, recessed portions 5 are provided for causing a difference in the flow velocity of the oil intruded into a gap 6b between the shaft end surface 3a and the guide member 4 so that a pressure gradient is generated, and the guiding member 4 is deformable in a direction of reducing the gap 6b between the guiding member and the shaft end surface 3a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
