Two-wheeled motor vehicle car cover

The present invention relates to a kind of two-wheeled motor vehicle that has the topped side cover car cover in two-wheeled motor vehicle main car frame side in detachable ground.

As everyone knows, accessory is bearing in when comprising on the main car frame parts that rearward stretch out from the two-wheel front bar, also comes the accessory of topped frame part with the car cover.As an example, see that the spy opens flat 3-167084 communique.

This car cover is generally combined by a plurality of separating parts, and the side cover of topped main car frame side is than the side fabric width of main car frame, and and generally is directly installed on main car frame etc. with Screw etc.

The rear portion of general two-wheeled motor vehicle is from the main car frame seat horizontal bar of equipment tubulose rearward, and when rear vehicle configuration accessory etc., its structure supports by welding or affixed carriage base part on this seat horizontal bar.

That is, for the seat horizontal bar being prolonged, just exists the one side of sacrificing the space with the pipe fitting of seat horizontal bar as reinforcing member around rear mudguard.

At this, in order to constitute rear vehicle, though the example that does not extend the seat horizontal bar is arranged, open in this example of putting down in writing on the clear 62-97892 communique real, be to seize rear mudguard on both sides by the arms from the reinforcement plate that is arranged at about vehicle frame, the tabular plate of seizing on both sides by the arms rearward extends, and rear mudguard is bearing on the back seat together with seizing bar on both sides by the arms.

Opening in the flat 1-150186 communique real, showing accessory is loaded in example on the rear mudguard.

Yet, even make vehicle with the way of additional side cover, but popular be to unload side cover, and main car frame has bigger side, in order to become the attractive parts of design, uses the design plan that it is exposed sometimes.

But at the example of above-mentioned the past, side cover surpasses the side amplitude of main car frame, accessories such as usually topped lubrication box and electric component and so on, and when unloading side cover, because these accessories etc. expose, the two-wheeled motor vehicle outward appearance is not good.
