[0058]A first embodiment will be described with reference to the drawings. The air conditioner case of the first embodiment constitutes a housing of an air conditioner mounted on a vehicle. The air conditioner takes in one or both of the air in the vehicle interior and the air outside the vehicle, adjusts the temperature and humidity of the sucked air, and blows it out into the vehicle interior, thereby air-conditioning the vehicle interior.

[0059] Such as figure 1 As shown, the air conditioner 1 of the first embodiment is composed of a blower unit 2 and an air conditioning unit 3 . A blower (not shown) and the like are arranged in a ventilation passage formed inside the blower unit 2 . In addition, an evaporator, a heater core, and the like (not shown) are arranged in the ventilation passage formed inside the air-conditioning unit 3 . The air conditioner 1 can cool the air taken in from the inside and outside air inlet 4 through the drive of the blower in the ventilation...

[0083] A second embodiment will be described. In the second embodiment, the structure of the concave portion 12 included in the first housing 10 is changed from the first embodiment, and the rest is the same as the first embodiment, so only the parts different from the first embodiment will be described.

[0084] Such as Image 6 As shown, in the second embodiment, the concave portion 12 faces the second housing main body 21 from the bottom 15 side so that the distance between the surface 12a on the inner wall portion 14 side of the outer wall portion 13 and the surface 12b on the outer wall portion 13 side of the inner wall portion 14 The sides gradually become larger and form a tapered shape. Therefore, the inner angle θ1 of the concave portion 12 of the first housing 10 has a value larger than 0°. However, also in the second embodiment, as in the first embodiment, the inner angle θ1 of the concave portion 12 and the taper angle θ2 of the tapered portion 23 have a relation...

[0092] A third embodiment will be described. In the third embodiment, a part of the structure of the protrusion 22 included in the second housing 20 is changed from the first embodiment, and the others are the same as the first embodiment, so only the parts different from the first embodiment will be described.

[0093] Such as Figure 10 with Figure 11 As shown, in the third embodiment, the convex portion 22 has a straight portion 25 between the tapered portion 23 and the second case main body 21 in which the change in plate thickness in cross-section is less than that of the tapered portion 23 . In the third embodiment, the angle θ8 formed between the surface 25a on the outer wall portion 13 side and the surface 25b on the inner wall portion 14 side of the straight portion 25 is 0°. Therefore, the surface 25a on the side of the outer wall portion 13 and the surface 25b on the side of the inner wall portion 14 of the straight portion 25 are formed in parallel.

Abstract

The purpose of the present disclosure is to provide an air-conditioning case so as to prevent squeaks without impairing seal integrity. A concave section (12) disposed on an end of a first housing (11) has: an inner wall part (14) positioned toward an air passage (30); an outer wall part (13) positioned outside the case; and a bottom part (15) connecting the inner wall part (14) with the outer wall part (13). A convex section (22) disposed on an end of a second housing (21) has a tapered part (23), the thickness of which in a cross-sectional view diminishes progressively from the second housing (21) toward the bottom part (15) of the concave section (12). The tapered part (23) fits between the inner wall part (14) and outer wall part (13) of the concave section (12). A taper angle (theta2)is formed by a face (23a) of the tapered part (23) facing toward the outer wall part (13) and a face (23b) of the tapered part (23) facing toward the inner wall part (14). The taper angle (theta2) isgreater than an interior angle (theta1) formed by a face (12a) of the outer wall part (13) facing toward the inner wall part (14) and a face (12b) of the inner wall part (14) facing toward the outerwall part (13).
