A drive block having a motor and a speed reducer is mounted on a rear portion of a body frame constituting a frame of the body of the electric cart, and power is transmitted from the drive block to the drive shaft, and power is transmitted from the drive shaft to wheels to travel. It has become.

とができる。[0003] On the other hand, it is desired that the electric cart be reduced in weight so that it can be easily handled. In particular, a light weight body frame is desired. Further, the rear portion of the body frame needs to have a structure not only to mount the drive block but also to straddle the rear wheels. In such a rear frame on which the drive block is mounted, it is necessary to satisfy two conditions of straddling the rear wheels and being lightweight. As a body frame having a rear frame that satisfies these two conditions, the inventor of the present invention has provided an inverted L-shaped or inverted U-shaped rear frame at the rear of the front lower frame in the process leading to the present invention. I thought about forming a body frame. In such a body frame, the rear frame has an inverted L-shape or an inverted U-shape, so that it can straddle the rear wheels.
The drive block must be mounted on the rear frame in the shape of a letter, and the rear frame can be straddled as described above and the drive block can be mounted simply by making the rear frame an inverted L shape or an inverted U shape. Therefore, the weight can be reduced.

フレームが破損しやすいという問題点がある。However, in this case, by making the rear frame for mounting the drive block into an inverted L-shape or an inverted U-shape, the rear wheels can be straddled and the weight can be reduced. The rear frame has an inverted L-shape or inverted U-shape, and the rear frame supports the moment generated by the load in the front-rear direction, and the rear frame supports the left and right rear wheel suspensions. The reverse U-shaped rear part is not affected by torsional force generated in the rear frame when the load of the suspension is not equal, or when the vehicle body falls over or impacts with other transportation means. There is a problem that the strength of the frame is low and the rear frame is easily damaged.
