<p>PROBLEM TO BE SOLVED: To adjust the opening of an air outlet. SOLUTION: A flap 4 is rotatably arranged in an air outlet 3 made through an enclosure 1 and a cam hole 14 is made through one end plate 11a of the air outlet 3. A cam 15 installed to one bearing shaft 104 of the flap 4 is inserted into the cam hole 14 which is divided into two cam hole sections, namely, a left cam hole section 14a and a right cam hole section 14B and two rotation regulating sections 16 are formed on the inner peripheral surface of each cam hole section 14A and 14B. The rotation regulating sections 16 of the left-side cam hole section 14B are positionally deviated from the rotation regulating sections 16 of the right-side cam hole section 14A by a prescribed interval along the upward moving direction (e) of the flap 4 so that the upper or lower part of the air outlet 3 may be operated by a prescribed interval r1 or r2 when the flap 4 is moved upward (d) or downward (e) and horizontally from the state where the air outlet 3 is completely closed.</p> |
