。 A front wheel steering mechanism, a rear wheel steering mechanism, a mode switching mechanism that selectively and reversibly transmits the steering direction and amount of steering of the front wheel steering mechanism to a rear wheel steering mechanism, and a lock that locks the rear wheels in a neutral position during front wheel steering. In a four-wheel steering vehicle equipped with a mechanism, two lock detection means detect a neutral lock state of the rear wheels by the lock mechanism, a steering angle detection means detects a rear wheel steering angle, and both lock detection means are in a locked state. What is claimed is: 1. A rear wheel lock detection device for a four-wheel steered vehicle, comprising lock determination means for detecting rear wheel lock when the steering angle detection means detects a neutral steering angle range.
