  • Patent number: 7611167
    Abstract: A fuel tank is provided which suppresses wave motion on the liquid surface of fuel which occurs when a vehicle accelerates or decelerates. A front wall and/or a rear wall of the fuel tank includes a plurality of steps formed integrally therewith. The liquid surface of the fuel striking the steps is dispersed, and wave motion on the liquid surface is thereby suppressed. Since the steps are formed in the front wall and/or the rear wall of the fuel tank, the volume of the tank is not reduced.

  • Publication number: 20050082810
    Abstract: A rod-like body made of a rubber material having an outside diameter which is substantially equal to the inside diameter of the guard pipe or an unexpanded resin material having a quality that the resin material expands sufficiently when heated in a paint baking process for the guard pipe is inserted, as a vibration damping material, into the interior of the guard pipe before the pipe is worked. Due to this, since the guard pipe can be made difficult to vibrate without making any substantial changes to the conventional vehicle body structure, the invention is effective in reducing noise generated while a vehicle is running without entraining a remarkable increase in production costs.
