PURPOSE:To aim at betterment in a sensation of refreshingness owing to dynamical pressure ventilation inside a car as well as improvements in sightability for a side window, by installing a fresh-air intake in a door mirror case, while interconnecting it to a throttle valve-cum-car blowoff port and an outer blowoff port along a side windowpane. CONSTITUTION:Air A taken in from a fresh-air intake 3 opened to a door mirror case 2 runs past an external blowoff port 8 along a side windowpane and then blows out along a windowpane 7. This outflow air B wipes clean waterdrops clinging to the windowpane 7 is blown to the inside of a car from an internal blowoff port 4 via a throttle valve 12 whereby dynamical pressure ventilation takes place. At this time, a blowoff quantity is adjustable by the throttle valve 12. With this constitution, refreshability inside the car is made yet better and sightability in the side window is improved. |
