A transaxle ( 1 ), having a hydraulic drive unit ( 20 ) and a pair of left and right wheel support units ( 2 L and 2 R), is suspended from a vehicle frame so as to be turnable around a turning-center axis oriented in a fore-and-aft direction of a vehicle. The hydraulic drive unit ( 20 ) comprises: a pair of left and right hydraulic motors ( 23 L and 23 R) having respective left and right horizontal motor shafts ( 23 b); a center section ( 22 ) formed therein with an oil passage for hydraulically connecting at least one of the hydraulic motors to a hydraulic pump, the center section having motor attachment surfaces onto which the hydraulic motors are attached; and a pair of left and right axle casings ( 2 L and 2 R) containing the respective hydraulic motors and supporting the respective motor shafts. The pair of wheel support units ( 30 L and 30 R), supporting respective left and right travel wheels ( 1 L and 1 R), are joined to respective outer ends of the left and right axle casings, and drivingly connected to the respective motor shafts ( 23 b).
