<p>PURPOSE:To prevent pitching of a vehicle body due to a projection part when a caster is run on the projection part of a road surface at running by fluctuating a first link and a second link together with a third link connecting to them, centering around respective supporting points. CONSTITUTION:One end part 9a of a first link 9 is fixed to the upper end part of a first caster 5a, and the other end part 9b is fixed to the upper end part of a wheel-in-motor 3. One end part 11a of a second link 11 is fixed to the upper end part of a second caster 5b, the other end part 11b is positioned on the other end part 9b of the first link 9, and a third link 13 is arranged between these end parts 9b, 11b. When the first caster 5a or the second caster 5b is run on a projection part of a road surface at running, the first link 9 and the second link 11 are fluctuated centering around respective link supporting points 9c, 11c together with the third link 13, and hence pitching of a vehicle body 1 is prevented.</p> |
