[0044] A first embodiment of the present invention will be described below with reference to FIGS. 1 to 10 .

[0045] The interior air-conditioning unit 10 is disposed inside an instrument panel (instrument panel), which is disposed in front of the vehicle compartment, substantially at the center region of the vehicle in the width direction (left-right direction of the vehicle). The interior air conditioner unit 10 includes a case 11 for forming an enclosure and an air passage through which air is blown toward the interior of the vehicle compartment. The casing 11 has a certain elasticity and is molded using a resin having excellent strength such as polypropylene.

[0046] The casing 11 has a dividing surface S (see a later-explained Figure 4 ), and the casing 11 can be divided into two left and right divided parts 11a and 11b at the interface S. The left and right divided parts 11a and 11b are integrally connected to each other by connecting means such as metal springs, co...

[0135] In the first embodiment described above, the recessed space 32 a is laid-drawn in the door width direction W from the outer side of the driven side gear 32 . That is, in the first embodiment described above, the recessed space 32a opens from the outer side of the driven side gear 32, and extends in the door width direction W toward the center side. However, in the second embodiment, as Figure 11 As shown, the recessed space 32a is stretched from the inner side of the driven side gear 32 in the door width direction W. As shown in FIG. That is, in the second embodiment, the recessed space 32 a is opened from the inner side of the driven side gear 32 and extends in the door width direction W toward the outer end.

[0136] Thus, the second embodiment can obtain the same operations and effects as those in the first embodiment.

[0137] Furthermore, in this embodiment, the air blown to the defroster opening 24 flows into the recessed space 32a, as Figure 12 This causes t...

Abstract

An air passage opening and closing device includes a case forming an opening portion, a sliding door, and a gear mechanism. The case has a case-side seal surface at two edges of the opening portion in a width direction of a door body of the sliding door, on which a first plate surface of the door body abuts. The gear mechanism includes a driven side gear molded integrally with the door body using resin. The driven side gear protrudes from a second plate surface of the door body on a side opposite to the first plate surface, and extends in parallel with a movement direction of the sliding door, at two edge portions of the second plate surface in the width direction. In addition, the driven side gear has a hollow space opened toward a direction parallel to the width direction.

Description

technical field [0001] The present invention relates to an air passage opening and closing device for opening and closing an opening portion of the air passage by using a sliding door, and a method of manufacturing the same. For example, the air passage opening and closing device is suitable for use in a vehicle air conditioner. Background technique [0002] Generally, a vehicle air conditioner using such an air passage opening and closing device is disclosed, for example, in US Patent No. 6,450,877 (corresponding to Japanese Patent No. 3824105). In the air conditioner of the related art, a sliding door including a plate-like door body is slidably provided in a housing for forming an opening portion of the air passage to open or close the opening portion of the air passage. [0003] In the related art, a sealing surface is formed on the side of the housing at the peripheral edge of the opening. When the sliding door closes the opening portion of the air passage, the flat p...
