<P>PROBLEM TO BE SOLVED: To give attitude variation such as fluctuation and restoration of inclination without complicating a constitution of a stroller. <P>SOLUTION: The stroller includes: a vertically expandable/contractable elastic member 34 provided between a base body 12 and an axle receptacle 30; and an attitude variation giving means 16 for producing electric energy so as to correspond to expansion/contraction of the elastic member 34 by vertical motion of a wheel 14 due to irregularities of a road surface at traveling when the stroller is set to a power generation mode, and giving attitude variation to the base body 12 by giving external force to the elastic member 34 to make it expand/contract when the stroller is set to an attitude variation giving mode. The attitude variation giving means 16 is constituted of an electric motor having a rotation shaft, a rack gear standingly provided on the axle receptacle 30, and a pinion gear mounted to the rotation shaft of the electric motor and engaged with the rack gear. <P>COPYRIGHT: (C)2012,JPO&INPIT |
