ABSTRACT:
A new and unique saddle-riding type motorcar having four wheels comprising two front wheels and two rear wheels, wherein each of the front and rear wheels has a balloon tire mounted thereon and only the front wheels are rotatably supported on axles in such a manner as to turn in both directions relative to the longitudinal axis of the motorcar and the latter is steered by steering the front wheels by means of a bar handle constituting a steering mechanism. The motorcar includes a frame structure comprising a pair of upper frames, a pair of lower frames and a plurality of spacer frames, said pair of upper frames comprising a pair of fore-end portions extending downward from a bent portion at a forward inclination angle and a pair of inclined portions extending rearward by a certain distance from said bent portion at a gentle downward slope, said pair of lower frames being fixedly connected to the pair of upper frames by way of a fore axle at their fore end and by way of vertically extending frames at their rear end and said spacer frames extending in the transverse direction relative to the upper and lower frames so as to connect one of the upper frames to the other and one of the lower frames to the other. A steering head is located at the bent portion of the upper frames. Supporting sections are disposed at both the end-parts of the fore axle and at the rearmost end-parts of the lower frames to support the wheels. A suspension mechanism may be disposed at least on one of the front wheels and the rear wheels and each of the rear wheels may include an independent driving axle adapted to be swingably supported by means of an independent swing arm and an independent suspension mechanism.
