<p>PROBLEM TO BE SOLVED: To form a driving force transmission device for a vehicle equipped with an electromagnetic pilot clutch mechanism with liquid-tight sealed structure without increasing the weight and cost of the device. SOLUTION: An electromagnet 13a constituting a pilot clutch mechanism 10d is supported by a yoke 14. A cylindrical portion 14a on the leading end side of the yoke 14 that is positioned on the other side of rotation members 10a and 10b, and a cylindrical portion 28a on the leading end side of a differential carrier 28 are fitted to each other. The gap of the circumference of the fitted portion is set to the minimum dimension capable of securing the coaxially of an outer case 10a and an inner shaft 10b, both of which are rotation members, thereby forming the fitted portion into liquid-tight sealed structure.</p> |
