It is difficult to get over 4, (25, 26).

However, each opening 28,2 as shown in FIGS.
With the shape of 9,30, when the deformed edge 101 (102) abuts the edges of the packings 24, (25, 26), this abutting portion creates a point-contacting contact shape, The stress acting on this contact portion is small. Therefore, the deformed edge
The 101 (102) can easily get over the edges of the packings 24, (25, 26) without being caught by the packings 24, (25, 26).

Moreover, since the deformed edge 101 (102) has an inclined shape or a circular shape, even after the edge 101 (102) has passed over the edges of the packings 24 (25, 26), the film damper
The 20 can move smoothly along the above-mentioned inclined shape or circular shape. Therefore, the packing 24, (2
5,26) can be prevented from being caught by the edge, and this can suppress the generation of abnormal noise.

In order to prevent the edge 101 (102) from being caught, the packing 24 (25, 26) may have a hexagonal shape as shown in FIG.

May be applied.

Also in the embodiment of FIG. 18, as in the embodiment of FIGS. 15 to 17, the edges 101 (102) of the openings 28, 29, 30 of the film damper 20 deformed by wind pressure are the packings 24, ( twenty five,
When abutting against the edge 121 (122) of 26), the abutting portion forms a point-contact type contact shape, so that the edge 101 (102) is the edge 121 (of the packing 24, (25, 26). 122). And this suppresses the generation of abnormal noise.

In addition, the deformed edge 101 (102) is the packing 24, (2
Even after overcoming the edge 121 (122) of the 5, 26), the film damper 20 can be moved smoothly along the inclined shape of the edge 121 (122).

In the embodiment of FIG. 18, the packing 24, (25, 26) has a hexagonal shape, that is, a shape having an edge inclined with respect to the moving direction of the film damper 20. In the embodiment in which the packing 24, (25, 26) is not provided like the embodiment, if the shape of the air outlet of the case 11 itself is the above-described shape, the same effect as that of the embodiment in FIG. 18 is obtained. It goes without saying that there is a problem.

Further, in the embodiment shown in FIG. 19, since the opening edges of the packings 24, (25, 26) are chamfered, the edge 101 (102) deformed by the wind pressure is applied to the packings 24, (25, 26). ), Even after contact with the chamfered portion 103, the edge 101 (102) slides over along the chamfered shape of the chamfered portion 103. Therefore, the edge 101 (102) easily gets over the chamfered portion 103, and generation of abnormal noise at this time can be suppressed.

In the embodiment shown in FIG. 19, the opening edges of the packings 24, (25, 26) are chamfered, but the packings 24, (25, 26) are provided as in the embodiment shown in FIG. It is needless to say that, in an embodiment not shown, the chamfering process is applied to the opening edge portion of the air outlet of the case 11 itself to obtain the same effect as that of the embodiment shown in FIG.
