<P>PROBLEM TO BE SOLVED: To provide a lubricant supply device that improves performance where a lubricant is sent by a rotation of a gear, vertically upward. <P>SOLUTION: The device includes: a case 2; a storage 3 that is arranged in the case and stores the lubricant; the gear 4 that is arranged in the case and sends the lubricant of the storage by rotation; and an oil path 5 that is formed between the case and an outer periphery of the gear and leads the lubricant sent by the rotation of the gear, vertically upward. The oil path includes: a side oil path which is a clearance in an axial direction of the gear between a side of the gear and the case; and an outer-peripheral-surface side oil path 52 which is a clearance in a radial direction of the gear between the outer peripheral surface of the gear and the case. At a part A where a radial width of the outer-peripheral-surface side oil path is narrow, an axial width of the side oil path is wider than a part B where the radial width of the outer-peripheral-surface side oil path is wide. <P>COPYRIGHT: (C)2013,JPO&INPIT |
