Since the rim and the peripheral edge of the upper plate are formed in the caulked part by overlapping, even if the protrusion is formed by punching or cutting and raising which inevitably causes a hole, the hole is caulked. Closed by the overlapping part in the part, which results in
No air leaks occur. Since the protrusion can be formed by punching or cutting and raising in this way, unlike the conventional throttle, the amount of material used in the outer box does not increase.

ることができる。In the fourth means, the projection of the outer box and the engaging portion of the mounting plate are engaged to connect the outer box and the mounting plate, and the projection of the outer box and the hanging metal fitting. When the outer box and the hanging metal fitting are connected to each other by engaging with the engaging part of, the projecting part is formed in the caulking part where the upper opening edge part of the box body and the peripheral part of the upper plate are overlapped. Therefore, even if a protrusion is formed by punching or cutting and raising which inevitably creates a hole, the hole is closed by the overlapping part in the caulking part, resulting in air leakage. There is no. Since the protrusion can be formed by punching or cutting and raising in this way, unlike the conventional throttle, the amount of material used in the outer box does not increase.
Moreover, since both the mounting plate engaging portion and the hanging metal fitting engaging portion are engaged with the protruding portion of the outer box, the number of protruding portions can be reduced.

In the sixth means, since the protrusion is formed in a bag shape, the strength is increased. In this case, in the seventh means, since the engaging portion is formed by cutting and raising, the engaging portion can be formed relatively easily, and the protrusion engaging with the engaging portion is as described above. Since it is formed in a bag shape having high strength, the engagement strength of these does not decrease.

が多くなることもない。According to this embodiment, the protrusion 38 of the outer box 35 and the engaging portion 27 of the mounting plate 24 are engaged with each other to connect the outer box 35 and the mounting plate 24. Since the protrusion 38 is formed in the caulking portion 39 in which the upper opening edge of the box body 36 and the peripheral edge of the upper plate 37 are overlapped with each other, the protrusion 3 is inevitably formed by punching out a hole.
8 is formed, its hole 38a (see FIGS. 3 and 4) is closed by the overlapping portion of the caulking portion 39, in this case the second caulking portion 36b of the box body 36. As a result, it is possible to prevent air leakage. And
Since it is possible to form the protrusion 38 by punching in this way, unlike the conventional throttle portion, the amount of material used for the outer box 35 does not increase.

寄与できる。Further, the protrusion 38 of the outer box 35 and the suspension fitting 31
When the outer box 35 and the suspending metal fitting 31 are connected by engaging the engaging portion 33 of the box, the projection 38 is formed on the upper opening edge of the box body 36 and the upper plate 37 in the same manner as described above. Since the peripheral portions of the caulking portions are formed in the caulked portions 39 that are overlapped with each other, even if the protrusions 38 are formed by the punching that inevitably causes the hole portions 38a, the hole portions 38a will overlap the caulking portions 39. In this case, the box body 36 is closed by the second caulked portion 36b. As a result, it is possible to prevent air leakage. Since the protrusion 38 can be formed by punching in this manner, the material used for the outer box 35 does not increase unlike the conventional throttle portion. As a result, the manufacturability can be improved and the cost can be reduced.
