Abstract

A wheel driving speed reducer includes a parallel shaft gear mechanism (22) that includes a parallel shaft gear (24,26), a planetary gear mechanism (16) that is provided on a rear stage of the parallel shaft gear mechanism (22) and includes planetary gears (48) and an internal gear (50) with which the planetary gears (48) internally mesh, and a casing (20) that accommodates the parallel shaft gear mechanism (22) and the planetary gear mechanism (16). A tooth portion (26A) of the parallel shaft gear (24) protrudes and extends into a gap (51), which is formed between the casing (20) and the internal gear (50) or a member (53) integrated with the internal gear (50), in an axial direction. The tooth portion (26A) of the parallel shaft gear (22,24,26) and the internal gear (50) or the member (53) integrated with the internal gear (50) overlap each other when seen in a radial direction.
