To provide an auxiliary wheel device for a motor cycle that, when the motor cycle is stopped, maintains an almost upright posture and prevents it from falling down, and to provide a motor cycle.SOLUTION: An auxiliary wheel device 1 for a motor cycle includes: a U-shaped auxiliary-wheel mounting body 7 having a beam portion 4 extending in leftward and rightward directions on a lower part and side parts of a vehicle body 3, and a left arm portion 5 and a right arm portion 6 continuously provided almost at right angles to the beam portion 4; a left auxiliary wheel 20 and a right auxiliary wheel 8; a swinging/rotating support portion 37 that supports the beam portion 4 such that the beam portion is swingable in the leftward and rightward directions and rotatable around a horizontal axis P of the beam portion 4; and a drive unit 9 that rotates the auxiliary-wheel mounting body 7. The beam portion 4 is rotated to allow switching between a lowered position where the auxiliary-wheel mounting body 7 is brought into contact with a road surface and a raised position where it is separated from the road surface. The beam portion 4 is swung to allow variable adjustments of vertical positions of the left auxiliary wheel 20 and the right auxiliary wheel 8 according to leftward and rightward inclinations of the road surface.SELECTED DRAWING: Figure 1

    【課題】自動二輪車が停止したときの略直立姿勢を維持し、倒れ防止を図る自動二輪車の補助輪装置及び自動二輪車を提供する。【解決手段】車体3の下部及び側部に左右方向に延設されるビーム部4、ビーム部4に対し略直角をなすように連設される左アーム部5及び右アーム部6を備えたU字形状の補助輪取付体7と、左補助輪20及び右補助輪8と、ビーム部4を左右方向に揺動可能でかつビーム部4の水平軸心Pまわりに回動可能に支持する揺動・回動支持部37と、補助輪取付体7を回動させる駆動部9とを有し、ビーム部4を回動させ、補助輪取付体7を路面に接地する下降位置と路面から離間する上昇位置との間で切り替え可能とするとともに、ビーム部4を揺動させ、路面の左右方向の傾斜に応じて左補助輪20及び右補助輪8の上下方向の位置を可変に調整できる自動二輪車の補助輪装置1。【選択図】図1
