Abstract
A four-wheel drive vehicle is provided in its drive mechanism with an adapter case assembly interposed between a transmission and a transfer case. The adapter case assembly consists of a cylindrical and hollow outer wall member securely interposed between the housing of the transmission and the housing of the transfer case. The outer wall member is integrally formed with a generally frustoconical partition wall member disposed inside the outer wall member and located around a power output shaft drivingly connecting the transfer case with the transmission. The partition wall member defines thereinside an inner chamber of a smaller volume, communicated with the inside of the transmission housing so that oil within the transmission can flow into the inner chamber, thereby preventing much oil from flowing out from the transmission into the adapter case assembly.
