PURPOSE:To conduct sufficient exhausting without requiring any power source such as electric power, etc., even if a wind pressure difference or a temperature difference is small and to be further used as a light collector. CONSTITUTION:An exhaust accelerator 1 generates an air flow to exhaust the air in a building out of the building, and comprises a hollow box 3 formed of a front plate 17 and a rear plate 19 opposed to one another, an inlet 5 provided at a lower part of the box 3, an outlet 7 provided at an upper part of the box 3, and a heat ray absorption glass plate 9 arranged between the plate 17 and the plate 19 in the box 3. At least the plate 17 is formed of a transparent or translucent material. A reflecting surface 11 opposed to the plate 17 side is formed at the plate 19, a heat insulator 13 is mounted outside the plate 19, and a roof member 21 for preventing invasion of rainy water into the box 3 is provided above the outlet 7. |
