A narrow inlet is formed on an inner side contacting a cavity. An extended outlet is formed on an end portion communicating with the outside. A diffusion part is formed to connect the narrow inlet with the extended outlet. A protrusion has a short length and an uniform thickness. Therefore, a vehicle sheet can be worn in a beautiful condition without being cut. In addition, the width of the contact surface can be reduced.</p> |
