PROBLEM TO BE SOLVED: To provide a ventilation device in which its fixing or removing operation can be easily carried out and its position alignment can be performed in respect to a side wall surface or the like. SOLUTION: This ventilation device is constructed such that a stopper section 16 forcedly contacted with the inner surface of a ventilation outer cylinder 1 is arranged at a fitting section 8 of a front louver 7 in an inverse contacting direction. With such an arrangement as above, when the fixing section 8 is inserted into the inner surface of the ventilation outer cylinder 1, a stopper section 16 receives a force from the ventilation outer cylinder 1 in an inverse contacting direction and is deformed, resulting in that at its fixing position, it is contacted with the inner surface of the ventilation outer cylinder due to its resistance against deformation and then its fixed state is kept. In addition, the stopper section is deformed in an inverse contacting direction to cause the stopper section 16 to be moved away from the inner surface of the ventilation outer cylinder 1 and the aforesaid fixed state is released. Accordingly, it is possible to fix or remove the front louver in an easy manner and then cleaning of the ventilation device can be easily carried out. |
