<P>PROBLEM TO BE SOLVED: To provide a lubricating oil supply device capable of enhancing supplying ability of a lubricating oil. <P>SOLUTION: The lubricating oil supply device includes a gear 7 disposed in a lower part inside a case 2 and rotated to be interlocked with rotation of a wheel, an oil receiving part disposed in an upper part of the gear and supplying the lubricating oil flowing in via a flowing port to respective parts of a power transmission device, a wall member having a pair of sidewall surfaces 22 and 23 opposed to each other in an axial direction sandwiching the gear and a prescribed wall surface 20 connecting the pair of sidewall surfaces in the axial direction and opposed to an outer peripheral surface 71 of the gear and an oil path 10 formed between the wall member and an outer peripheral part of the gear. The gear sends out the lubricating oil accumulated in the case by rotation toward the flowing port via the oil path. The sidewall surfaces have protrusion parts 30 formed along the oil path and protruding toward side surfaces 74a of the gear in the axial direction. A width W1 of a gap 10b between the protrusion part and the side surface of the gear on a downstream side in the flowing direction of the lubricating oil flowing in the oil path is smaller than that on an upstream side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
