PROBLEM TO BE SOLVED: To provide a two-wheeler fitted with auxiliary wheels structured as accomplishing a reduction of the fatigue of a rider and preclusion of the risk of falling aside at the time of being stopped, capable of eliminating a degradation of the vehicle body attitude occurring in association with the accomplishment of the described purpose, i.e. a fatigue owing to the situation that the verticality to the road surface at the time of riding can not be kept to result in running in the inclined condition to the left or right or lasting of the stopped condition, instability and unease of the rider at starting next time, performing a low-speed running and stopping stably without hindering the body from having equilibrium in the normal driving operation, and able to be disseminated widely to the public. SOLUTION: Degradation of the vehicle body attitude with varying road surface likely generated at the time of self-supported running with auxiliary wheels is eliminated by the use of supporting part auxiliary wheels able to be fixed and make swinging on the left and the right individually, two-wheel self-supported running due to the equilibrium sense of the rider in the normal driving, and an auxiliary wheel supporting force adjusting function with a hand-operated lever allowing the rider to make manipulation appropriately, and the rider can handle the vehicle body in low-speed running or upon stopping or getting off the vehicle while he omits having his feet on the ground with ease by displaying the conditional notification to the rider.
