Claims

[Scope of utility model registration request]

Both drive shafts connected to both side gears of the differential, which is the non-drive side during two-wheel drive, are each divided into two parts, and the two divided shafts are connected so as to be relatively rotatable, and these two sets of both divided shafts are connected. In a four-wheel drive vehicle in which the disconnection mechanism is disconnected via a disconnection mechanism, the disconnection mechanism is assembled to the outer periphery of the connecting portion of the two split shafts in the first drive shaft so as to be movable in the axial direction, and the disconnection mechanism is assembled so as to be movable in the axial direction. a coupling sleeve that connects and disconnects the two split shafts; and an operation that is assembled in parallel to the first drive shaft at a portion corresponding to the connecting portion and reciprocates intermittently by a predetermined amount in the axial direction by remote control. an operating lever that is assembled to the actuating rod and engages with the coupling sleeve to selectively move it to the coupled side and the non-coupled side of both split shafts, and an inner split of the second drive shaft; The shaft is configured to fit into the side gear so that it can move only in the axial direction, and the second
a coupling rod that is axially movably and rotatably fitted into the outer split shaft of the drive shaft and disconnects and connects the coupling with the outer split shaft by the axial movement; and the first drive shaft. a connecting rod that extends coaxially and axially movably through the coupling rod to connect the coupling sleeve to the coupling rod, and connects the coupling rod to the second drive shaft through a bushing. A drive shaft disconnection mechanism in a four-wheel drive vehicle, characterized in that it is supported on an outer side split shaft.
