装置。[Scope of Claim for Utility Model Registration] A slip prevention device for a four-wheel drive vehicle equipped with a differential device that evenly distributes the driving force from the vehicle drive source to the front and rear wheels, which is a longitudinal load applied to each wheel of the vehicle. a differential limiting device that limits the differential of the differential; a rotational speed detection means that detects the rotational speed of each wheel; and when the vehicle speed is 0, the rotation of the a derailed wheel detecting means for detecting the idle wheel with the highest rotational speed as a derailed wheel based on the detection result of the speed detecting means; a first slip prevention means that drives a limiting device to limit differential movement of the differential device and drives the vertical load adjustment member to increase a vertical load applied to the derailed wheel; idling wheel determining means for determining whether or not there is a idling wheel other than the detected derailed wheel based on the detection result of the rotational speed detecting means during operation of the means; A second idling prevention means that drives the vertical load adjustment member to increase the longitudinal load applied to the idling wheel when it is determined that there is a idling wheel other than the wheel that has come off the wheel. A slip prevention device for four-wheel drive vehicles.
