Abstract

The disclosed left-right wheel drive device (30) includes first tubular surface portions (21), second tubular surface portions (22), and third tubular surface portions (23). The first tubular surface portion (21) is formed into a tubular surface shape along an outer circumference of a driven gear (8) and serves as a passage that transmits, to a lower side of counter shaft (6), lubricant collected under output shaft (9). The second tubular surface portion (22) is formed into a tubular surface shape along an outer circumference of a first counter gear (4) and collects lubricant under the counter shaft (6). The third tubular surface portion (23) is formed into a tubular surface shape along an outer circumference of the first counter gear (4), is arranged between a first bearing (27) of the driven gear (8) and the first counter gear (4), and serves as a passage that transmits, to an upper side of the output shaft (9), lubricant collected by the second tubular surface portions (22). The upper surface portion (24) is formed into a surface shape connected to an upper end of the third tubular surface portion (23), is arranged over the first bearing (23), and includes a first oil hole (25) that supplies lubricant to the first bearing (27).
