置。[Scope of Claim for Utility Model Registration] 1. In an industrial vehicle in which one of the front and rear wheels is a steering wheel and the other is a drive wheel, a differential installed in a traveling drive device is capable of being switched on and off. A differential lock is provided, and a clutch is installed on each axle shaft that connects the differential to the left and right drive wheels, and when the steered wheels turn, the differential is activated and the differential is rendered inactive. A turning device for an industrial vehicle, further comprising an operating device for disengaging a clutch on the inner side in the steering direction to bring the drive wheel on the inner side in the steering direction into an idle state. 2. In an industrial vehicle in which one of the front wheels and rear wheels is a steering wheel and the other is a drive wheel, a clutch is attached to the axle shaft that connects the left and right drive wheels to the differential installed in the travel drive device. A brake is installed on each axle shaft on the differential side, and when the steering wheel turns, the clutch on the inside in the steering direction is separated and the drive wheel on the inside in the steering direction is idle. A turning device for an industrial vehicle, comprising: an operating device for applying a brake on the inner side in the steering direction to fix an axle shaft on the inner side in the steering direction;
