<p>PROBLEM TO BE SOLVED: To prevent the leakage of lubricating oil filled in an inner space of a differential gear case of a differential gear toward the inner space of a clutch device when the differential gear and the clutch device are mutually closely positioned for disposing them in a compact space. SOLUTION: The clutch device 12 is provided with a solenoid 40 which is stored in the inner space 28 of a cultch housing 27 and operates to disconnectably transmit the driving force inputted in the clutch housing 27 to an input shaft 17 and a support body 43 which is externally fitted around one end part 14a of the differential gear case 14, connected to the differential gear case 14, and supports the solenoid 40. A clearance 49 communicating the inner space 28 of the clutch housing 27 to an atmosphere side is formed between mutual opposite surfaces 47 and 48 in a mutual fitting part between the one end part 14a of the differential gear case 14 and the support body 43. A groove 50 extending along the circumferential direction of an axis 15 is molded, at least, in either one of the both opposite surfaces 47 or 48.</p> |
