Abstract
A transmission includes: a plurality of annular first engagement members; a fitting member having outer teeth spline-fitted to inner teeth of the first engagement members, the fitting member being configured to be rotatable around a predetermined rotation axis; a plurality of annular second engagement members configured to be engaged with the first engagement members; a lubricating oil supply portion configured to supply a lubricating oil to the fitting member; and a transmission case configured to accommodate the first engagement members, the fitting member, the second engagement members, and the lubricating oil supply portion. The lubricating oil supply portion is provided on an inner wall of the transmission case, and a discharge portion of the lubricating oil supply portion which ejects the lubricating oil is configured to eject the lubricating oil toward a portion where the first engagement members and the fitting member are spline-fitted to each other.
