PROBLEM TO BE SOLVED: To provide a drive unit in which a sealing structure for a motor can be simplified.SOLUTION: Oil flows through an oil passage 89 in a motor shaft as shown by an arrow (3). Accordingly, the oil does not leak into a motor case 49. The inside of the motor case 49 is so-called "dry". Although wires 123 extending from a stator 71 penetrate the motor case 49 and extend to the outside, no sealing measures are required in the penetration portion. Thus, a seal in the penetration part may be a simple one such as a dust seal. |
