Abstract

See full text

A reduction gear case (29) of a planetary gear reduction mechanism (28) is mounted on a reduction gear mounting part (18C) of an axle tube (18). A carrier (33) is provided with a wheel mounting part (33B) projecting outside of the reduction gear case (29). A wheel (2) is mounted on the wheel mounting part (33B) and an oil seal (39) is disposed between an outer peripheral surface of the wheel mounting part (33B) and an inner peripheral surface of the front wheel (2) of the reduction gear case (29). As a result, the oil seal (39) can be exposed by removing the front wheel (2) from the wheel mounting part (33B) in the carrier (33). On the other hand, a brake mechanism (40) is disposed on the inner peripheral side of the reduction gear mounting part (18C). Therefore, the brake mechanism (40) can be exposed by removing the front wheel (2) from the wheel mounting part (33B) in the carrier (33) and the planetary gear reduction mechanism (28) from the reduction gear mounting part (18C).
