Patent attributes
A lubricant oil supplying apparatus (1-1) provided for a power transmission apparatus (1) having an accumulating part (9), a rotating member (7) rotating interlockingly with rotation of a drive wheel to feed a lubricant oil in the accumulating part, and an oil receiving part (8) disposed above in the vertical direction than the rotating member, and supplying the lubricant oil to the oil receiving part, in which a passage member (10) for guiding the lubricant oil fed by the rotating member to the oil receiving part is provided. The passage member has: a first component part (11) provided so as to be opposed to the rotating member along a circumferential direction and forming, between the rotating member and itself, a first passage (13) to which the lubricating oil flows; and a second component part (12) forming a second passage (14) for guiding the lubricant oil in the first passage to the oil receiving part, and the second passage is connected to the first passage on the upstream side in the flow direction of an outflow port (13b). The lubricant oil supplying apparatus further includes a suppression structure (7, 10) of suppressing flow of the lubricant oil in the first passage from a connection part (13c) to the second passage toward the outflow port.
