ABSTRACT:
A vehicle with two parallel wheels according to the invention has split steps (2L,2R), a vehicle body, a pair of wheels (4L,4R) coaxially parallelly arranged, a pair of wheel drive units for independently driving the wheels (4L,4R), and a pair of step run-on assisting mechanisms (8L,8R) arranged corresponding to the wheels (4L,4R) and changing the degree of dependency of step run-on operation. The step run-on assisting mechanisms (8L,8R) each have an assisting turning member (15) having a circular arc support surface with a curvature radius greater than the radius of the wheel (4L,4R) and having its turning center in front, in the travel direction, of the rotation center of the wheel, a link member (16) rotatably supporting the assisting turning member (15), and a damper (25, 26) for changing, according to the speed at which the assisting turning member (15) collides with a step, force retaining one end of the link member (16).
