An in-wheel motor unit for vehicles, and a displacement absorption mechanism assembly method for the same

Japanese Patent JP6011718

B2

A vehicular in-wheel motor unit that makes it easy to attach a displacement-absorbing mechanism is provided. Said displacement-absorbing mechanism (B), which couples a drive output shaft (10) from a main drive unit (A) and a wheel-hub shaft (70) supported with respect to an unit housing (1) by a hub bearing (71), has the following: an output-shaft-side drive-transmission mating section (58) where a first internally toothed part (56) of the drive output shaft (10) meshes with a first externally toothed part (52) on a gear-coupling shaft (50); and a hub-shaft-side drive-transmission mating section (59) where a second internally toothed part (57) of a wheel-hub shaft (70) meshes with a second externally toothed part (54) on the gear-coupling shaft (50). The end of the wheel-hub shaft (70) facing away from the main drive unit (A) is provided with an opening (70b) into which the gear-coupling shaft (50) can be inserted, and an end-cap sealing member (76) that blocks said opening (70b) is provided in the wheel-hub shaft (70).
