The oil outlet port opens to a bottom portion in one end side of a transmission case in a vehicle body front-back direction and a vehicle body left-right direction. The oil outlet port takes out a lubricating oil from an interior of the transmission case. The partition part divided an internal space of the transmission case into a first space zone along a sidewall portion of the transmission case, and a second space zone other than the first space zone. The partition part brings the first space zone into a sealed state.
