ABSTRACT:
A transaxle (1), having a hydraulic drive unit (20) and a pair of left and right wheel support units (2L and2R), 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 (23L and23R) having respective left and right horizontal motor shafts (23b); 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 (2L and2R) containing the respective hydraulic motors and supporting the respective motor shafts. The pair of wheel support units (30L and30R), supporting respective left and right travel wheels (1L and1R), are joined to respective outer ends of the left and right axle casings, and drivingly connected to the respective motor shafts (23b).
