Abstract: A motorized wheelchair having transmission rollers to transmit the rotation of rear wheels to front wheels while being disposed at a transmission position between circumferential surfaces of front and rear wheels, a roller supporting arm for rotatably and oscillatingly supporting the transmission rollers in the front-rear direction of the wheelchair, and transmission roller pressure-contact springs for urging the roller supporting arm in a direction of the transmission position. An operation lever constrains the roller supporting arm in an interlocking manner in the direction away from the transmission position when being at the regular position, and releases the constrains when the operation lever being at the working position so as to allow the transmission rollers to be disposed at the transmission position.

Abstract: A differential steering type motorized vehicle is capable of directly steering a front wheel by the turning operation of handlebars, and performing on-the-spot turning around a central position of a vehicle body together with differential rotation type control of drive wheels, and comprises the front wheel as one wheel supported by a lower end of a handlebar shaft provided below the handlebars and located at a central position along the lateral axis, rear wheels as a pair of right and left omnidirectional wheels, a pair of drive wheels which are located between the front wheel and the rear wheels, and drive-controlled so as to perform the differential steering caused by differences in rotational direction and rotational speed between the rear wheels, a rotational position sensor for detecting the turn direction and the turn angle from the reference position of the handlebars to be turned in the right or left direction, and a motor drive wheel control means for controlling the rotational direction and the rota

Abstract: A motorized wheelchair having right and left motorized rear wheels, and fixed front wheels in which a plurality of rollers rotatable in a direction orthogonal to an alignment direction of wheels are disposed therearound, comprises transmission rollers to transmit the rotation of the rear wheels to the front wheels while being disposed at a transmission position between circumferential surfaces of front and rear wheels in order to easily perform the switching to the four-wheel drive as necessary, a roller supporting arm for rotatably and oscillatingly supporting the transmission rollers in the front-rear direction of the wheelchair, and transmission roller pressure-contact springs for urging the roller supporting arm in a direction of the transmission position so as to be pressure-contacted with the circumferential surfaces of the wheels at the transmission position.
