<p>PURPOSE: To sufficiently secure the stroke length in the vertical direction of a front wheel by integrally forming the front end sections of a front frame and a lower frame, and supporting an arm supporting the front wheel on an integrally formed portion. CONSTITUTION: A front cage 1 is provided with an upper frame 3 arranged nearly horizontally on a vehicle, a lower frame 4 arranged nearly horizontally below the vehicle, a front frame 5 connecting the front end sections of the upper frame 3 and the lower frame 4, a main frame 6 connecting the rear end sections of the upper frame 3 and the lower frame 4, and a down frame 7 connecting the front frame 5 and the lower frame 4, and it is formed into a cage shape by these frames. Since the front end sections of the front frame 5 and the lower frame 4 are integrally formed, the length of an arm supporting a front wheel can be extended without widening the width of the vehicle, and the stroke length in the vertical direction of the front wheel can be sufficiently secured.</p> |
