Abstract: Guide walls are extended upwardly along the side edges of a front fender mounted between a pair of front forks of a two-wheeled or three-wheeled vehicle. These guide walls streamline the air flowing along the front fender and cause the volume of air flowing toward an engine installation position to be increased. Disturbance of air due to the front forks can be reduced to a minimum by these guide walls and outer plates which are branched from the guide walls so as to cover the outer portions of the front forks so that the air resistance can be decreased. The guide walls reinforce the front fender and give them rigidity sufficient to prevent vibration of the front fender when the two-wheeled or three-wheeled vehicle is running.

Abstract: A thermal insulator comprises an expanded resin body having embedded therein an evacuated powder insulation portion which consists of fine powder and a container of film-like plastics or a film-like composite of plastics and metal for enclosing the powder. The resin body has been expanded by a Freon gas as a blowing agent. Since a Freon gas has a larger molecular diameter than the constituent gases of air, it is less likely to permeate through the container than air. Thus present invention provides a novel composite insulator which fully utilizes the benefits of vacuum insulation without necessitating a strong and costly material for a vacuum container.
