ABSTRACT:
An output shaft is supported by means of a ball bearing at one end, a radial needle bearing and a thrust bearing. The ball bearing is arranged for supporting the output shaft against most part of radial load. On the other hand, the trust bearing is arranged for supporting the output shaft against the thrusting force which is exerted on the output shaft while the engine driving torque is transferred therethrough. Such construction reduces radial and thrusting stress to be exerted on the needle bearing. Therefore, the radial needle bearing to be used in the shown construction is required substantially small load capacity and thus can be satisfactorily small for allowing the transaxle unit to be designed compact.
