摘要： In a four-wheel drive vehicle, a first transaxle is disposed on one of front and rear sides of a power unit so as to be drivingly connected to one of front and rear ends of a transmission output shaft of the power unit. A second transaxle is disposed on the other of the front and rear sides of the power unit. A clutch-brake unit includes a clutch and a parking brake. An input shaft of the second transaxle is divided in the clutch-brake unit into upstream and downstream divisional shafts. The upstream divisional shaft is drivingly connected to the other of the front and rear ends of the transmission output shaft. The downstream divisional shaft is drivingly connected to right and left second drive wheels carried by the second transaxle. The clutch is interposed between the upstream and downstream divisional shafts. The parking brake is disposed on the upstream divisional shaft. When the parking brake is shifted to a braking state, the clutch having been disengaged is automatically engaged.
