PROBLEM TO BE SOLVED: To provide a wheel-mounted work vehicle configured so that a vehicle body is suppressed from being steered when an occupant unintentionally touches an operation lever.SOLUTION: The wheel-mounted work vehicle comprises: a front vehicle body 2 and a rear vehicle body 3 connected bendably through a connection shaft 4; left and right steering cylinders 5 and 6, provided between the front vehicle body 2 and the rear vehicle body 3, which steer the front vehicle body 2 in left and right directions relative to the rear vehicle body 3; and a steering lever device 24 steered and operated by a driver. The steering lever device 24 comprises an operation lever 28 which can be moved in front and back directions and in left and right directions, and a guide member 29 which guides movement of the operation lever 28. The guide member 29 is provided with a guide groove 30 for steering with which the operation lever 28 movably engages when steering by the operation lever 28 is performed and a guide 31 for prohibiting steering with which the operation lever 28 engages when the steering by the operation lever 28 is prohibited.SELECTED DRAWING: Figure 4
