PROBLEM TO BE SOLVED: To reduce the number of components, manufacturing cost of the components, and assembling man-hours by sharing a common spacer 37b disposed between two curved plates 31 in a speed reducer B, in an in-wheel motor driving device 21 applying a cycloid speed reducer as the speed reducer B.SOLUTION: Two inner pin bearings 37a are axially disposed to one inner pin 37 through a common spacer 37b to bring the inner pin bearings 37a and pin holes 36 of two curved plates 31 into contact with each other, and the common spacer 37b is used as a spacer for restricting axial positions of two curved plates 31, thus the number of components can be reduced, manufacturing costs of the components can be reduced, and further the assembling man-hours can be reduced.SELECTED DRAWING: Figure 2 |
