Abstract
A lubricating structure for a transmission includes: a case that includes a center support fixation portion that extends from the inner peripheral surface toward the radially inner side, and that houses the transmission on the first side of the center support fixation portion in the axial direction of the transmission; a center support that is press-fitted into the center support fixation portion, that rotatably supports an input shaft of the transmission, and that rotatably supports a clutch drum of the transmission; a bearing provided between the clutch drum and the center support in the axial direction; an oil reservoir portion formed on the center support on the second side of the center support fixation portion in the axial direction to open on the upper side in the vertical direction, the second side being opposite to the first side; and an oil passage formed in the center support, one end of the oil passage opening in the oil reservoir portion, and the other end of the oil passage opening in a space between the clutch drum and the center support in the axial direction.
