STRUCTURE FOR LUBRICATING TRANSMISSION

摘要

An oil feeding member (100), catching oil picked up by a gear, includes a gutter guiding the oil from one end to the other end of a transmission in its axial direction. The gutter is comprised of a first gutter (131) and a second gutter (132) arranged parallel to the first gutter. A portion of the oil feeding member closer to the one end includes a catching wall (124) standing between the first and second gutters, catching the oil picked up by a speed change gear (21, 22) serving as the gear, and guiding the oil into the first gutter. A transmission case (2) includes a guiding portion (150) guiding, into the second gutter, the oil picked up by the speed change gear and deposited on a ceiling surface (2c) of the transmission case.
