PURPOSE:To prevent damage to a steering chain and a chain sprocket by mounting a fender for them solidly as in a single body. CONSTITUTION:When steering wheel is turned to the left and right to swing the steering chain 11, consequently the chain sprocket 5 also, to the left and right, the steering wheel 1 will turn to the left and right, when a fender F1 at the same time rotates together with the steering chain 11 or chain sprocket 5 as in a single body. Thus the fender F1 rotates simultaneously with the steering chain 11, chain sprocket 5 and steering wheel 1, so that their relative positions do not change and the fender covers them at all times. |
