Claims

[Scope of utility model registration request]

Both drive shafts connected to both side gears of the differential, which is on the non-drive side during two-wheel drive, are each divided into two parts, and both 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, the disconnection mechanism is installed in parallel with one of the drive shafts at a location corresponding to a connecting portion of one of the drive shafts of a case that accommodates both drive shafts. an actuating rod that is attached to the actuating rod and reciprocates intermittently in the axial direction by a predetermined amount by remote control; and a first coupling member that is assembled to the actuating rod and provided on one drive shaft side, and engages with the first coupling member that connects the two split shafts. an operating lever for selectively moving the drive shaft to a coupled side and a non-coupled side; and a control lever that passes through the one drive shaft so as to be movable concentrically and in the axial direction, and the first coupling member is provided on the other drive shaft side. A connecting rod connected to a second coupling member, and an intermediate portion of the connecting rod connected to one of the split shafts so as to be able to swing in the radial direction, and one swinging end of the connecting rod being attached to a portion of the connecting rod. A swinging arm to be engaged is provided at the other swinging end of the swinging arm, and the swinging arm is swung by the action of centrifugal force, so that the swinging arm is mounted at the other swinging end of the swinging arm. A drive shaft disconnection mechanism for a four-wheel drive vehicle, characterized in that the connecting rod is configured to include a vertical weight that presses the divided shafts toward the uncoupled side.
