Stability is improved by expanding right and left rear wheels for steering in accordance with the width of the bench seat, and overturning is prevented by suppressing an inclination in a small amount using a link mechanism capable of setting a maximum slope angle while synchronizing the right and left rear wheels with the inclination of the vehicle body so as not to impair the lightness of the drive of the bicycle. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
