<P>PROBLEM TO BE SOLVED: To provide a lubricating oil supply device improved in an ability of feeding a lubricating oil upward by a gear. <P>SOLUTION: The lubricating oil supply device includes: a casing 2 of a power transmission device where a reservoir is formed; a gear 7 disposed in the casing and having outer gear teeth 77; a wall member having side wall faces 22, 23 opposing to each other in an axial direction across the gear and a prescribed wall face 24 axially connecting the pair of side wall faces and opposing to the gear outer circumference face 71; an oil path 10 extended in a circumference direction between the gear and the wall member and communicating with the reservoir; a protruding member 30 protruding in the axial direction from the side face of the gear toward the side wall face; and guiding sections 22a, 23a guiding the lubricating oil. The lubricating oil in the reservoir is fed upward by the rotation of the gear through the oil path. The protruding member has a guide face directing the front side in the rotation direction. The outside in a radial direction of the guide face is at a position backward more in the rotation direction than the inside of the guide face, and feeds the lubricating oil lateral in the gear to the radially outside when the gear is rotated. The guiding section guides the lubricating oil fed by the guide face to the outer teeth. <P>COPYRIGHT: (C)2012,JPO&INPIT |
