(Effects of the Invention) According to the present invention, since a connecting member is installed between the pivot portion of the lower arm relative to the side frame and the stationary side of the steering device supported on the vehicle body side,
This connecting member functions as a stay for the sight frame,
Therefore, when the vehicle is running, the side frame is prevented from bending due to external force applied to the front wheels. Therefore, the external force applied to the front wheels is suppressed from being transmitted to the driver who steers the front wheels, and as a result, the external force applied to the front wheels is reduced to 1! The convexity of h-sensation is prevented. Moreover, in this case, since the connecting member connects the pivot portion of the lower arm relative to the side frame and the stationary side of the steering device, even if an external force is applied, this connecting member will prevent the steering from bending. Movement relative to the steering device is prevented. As a result, the steering operation of the driver and the front wheels when steering! /1 will match more accurately, and therefore, improved steering stability will be achieved.
