Claims

[Scope of utility model registration request]

In a four-wheel drive vehicle equipped with a driveshaft disconnection mechanism that disconnects and disconnects a power transmittable connection between a side gear and a side gear shaft that constitute a differential that is on the non-drive side during two-wheel drive, the disconnection mechanism A friction engagement means that connects the side gear and the side gear shaft by operating with a thrust in the direction, and a pair of cam members, which move in directions that separate from each other during relative rotation to apply thrust to the friction engagement means. a first cam means that acts on one cam member of the cam means to cause relative rotation between the two cam members to operate the cam means; second cam means acting on one cam member and rotating both cam members in the same direction;
A driveshaft disconnection mechanism for a four-wheel drive vehicle, comprising a second operating means that operates the second cam means when the operating means releases the operation of the first cam means.
