<p>PURPOSE:To improve the weight balance and facilitate getting on and off by bending the front section of the frame of a tricycle obliquely upward to arrange a front wheel and mounting batteries at the middle portion containing the center of gravity of an isosceles triangle frame formed with front and rear wheels. CONSTITUTION:The front section 1a of an isosceles triangle-shaped frame 1 is bent upward to provide a front wheel 4, the rear section 1c is obliquely lifted then made horizontal, and rear wheels 3 are pivotally fitted. The front wheel 4 is arranged so that the center of gravity of the frame 1 is located at the middle section of the frame 1. A plate 6 is fitted to the frame 1, the front section is formed into a foot rest section 6a, the horizontal portion of the rear section is formed into a horizontal floor section 6b, and the center of gravity position is contained in the floor section 6b. Batteries 7 mounted on the horizontal floor section 6b are located at the center of gravity position, the weight balance of a car body is improved, and the getting on and off is facilitated because the center of gravity position is low.</p> |
