Abstract:
1. A lubricant oil supplying apparatus provided for a power transmission apparatus having a storage part that stores lubricant oil, a rotating member connected to a drive wheel of a vehicle and feeding the lubricant oil in the storage part by rotating interlockingly with rotation of the drive wheel, and an oil receiving part, in which the lubricant oil is supplied from the oil receiving part to a part to be lubricated, and supplying the lubricant oil to the oil receiving part, the lubricant oil supplying apparatus comprising: a passage member that guides the lubricant oil fed by the rotating member to the oil receiving part, wherein the oil receiving part is disposed above the rotating member in the vertical direction, the passage member includes a first component part that is provided so as to be opposed to the rotating member along a circumferential direction of the rotating member and forms, between the rotating member and itself, a first passage in which the lubricating oil fed by the rotating member flows, and a second component part that forms a second passage for guiding the lubricant oil in the first passage to the oil receiving part, the first component part includes a side wall opposed to a side face of the rotating member and a curved part opposed to an outer peripheral face of the rotating member, the second passage is connected to the first passage via an opening formed in the curved part, and the opening is disposed on an upstream side in a flow direction of an outflow port formed on a downstream side in a flow direction of the lubricant oil along a rotation direction of the rotating member in the first passage, and the lubricant oil supplying apparatus further comprises a suppression structure that suppresses flow of the lubricant oil in the first passage from the opening toward the outflow port and promotes flow of the lubricant oil toward the second passage.
