PURPOSE:To readily and exactly install a ventilator consisting of a motor and blades in a body case on a ceiling and duct and pipes. CONSTITUTION:In a ventilator incorporating a motor and blades 6 in a body case 1, clamping fixtures 2 are provided at four corners at the upper surface of the case 1. Each of the fixtures 2 is formed in deformed Z shape in cross section, with a longitudinal long hole 11 in X direction at one surface, and with a longitudinal cutout hole 12 in Y direction at the other surface. The fixture 2 also has a bent portion 13 bent inwardly at the end surface of the hole 12. According to this configuration, even if a hanging bolt 3 is previously implanted into a ceiling 4 to thereby decide the position of a duct 9, the duct 9 can be readily positioned by the rotary motion of the body case 1 at the stationary side via the fixtures 2 as a fulcrum and size controlling operation of the long hole 11, and the body case 1 and the duct and pipe can be readily and exactly installed on the ceiling and therearound. |
