Claims

[Claims for Utility Model Registration] 1. In a four-wheel drive vehicle in which the rear wheels and the front wheels connected to the front wheel power take-off shaft are respectively driven, a low-speed gear that is attached to the front wheel power take-off shaft via a one-way clutch. and a high-speed side gear rotatably attached to the front wheel power take-off shaft, and a high-speed side gear that is slidably fitted to the front wheel power take-off shaft and can be freely engaged and disengaged from the high-speed side gear in response to a steering operation of a steering device. A high-low speed switching device having an engaging pawl clutch body is provided in the front wheel power extraction case,
A front wheel speed increasing device for a four-wheel drive vehicle, characterized in that a drive section for sliding the pawl clutch body is provided outside the front wheel power extraction case. 2. A rotatable shift arm connected to a pawl clutch body and a first link connected to a drive unit are arranged substantially parallel, and the shift arm and the first link are connected to a second link. 2. The four-wheel drive vehicle according to claim 1, wherein the shift arm and the second link are rotatably connected through the shift arm and are set to be substantially perpendicular to each other when the drive section is operated. Front wheel speed increase device.
