<P>PROBLEM TO BE SOLVED: To achieve a vehicle for easily changing its posture to an inclined state, and capable of maintaining a proper state in the posture. <P>SOLUTION: This vehicle includes a wheel rotatable around a rotary shaft. The vehicle includes an posture control mechanism for controlling the posture of the vehicle. The wheel has a grounding part positioned under the rotary shaft and groundable on the ground surface when the vehicle operates. When a virtual plane including the rotary shaft and having a normal direction becoming a horizontal direction is assumed as a first virtual plane, a crossing line between the grounding part and the first virtual plane has a straight line part and a curved part, and a first point for satisfying the following (1) condition is included in a point on the curved part. (1) A second virtual plane including the first point and orthogonal to the first virtual plane, that is, the second virtual plane where the normal direction of the second virtual plane becomes the tangent direction of the curved part in the first point, is positioned under the center of gravity of the vehicle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
