Problems solved by technology
Therefore, the sealing member is bonded to the lower door by manual work, and its workability is poor, which becomes a cause of high cost.
In addition, due to manual work, the quality of the adhesive structure of the sealing member may not be stable.
[0006] In JP-A-2002-307929, it is recorded that as the sealing member, it is made of a rubber-like elastic material, and other examples of the main scheme of the sealing member having a lip-shaped sealing shape can also be used, but this other example is only a narration of the article. Since the arrangement relationship between the sealing member and the inner cylindrical portion on the housing side is not shown, the specific sealing mechanism between the sealing member made of rubber-like elastic material and the sealing surface on the housing side is unclear.

Embodiment Construction
[0052] One embodiment of the present invention will be described below based on the drawings. figure 1 is a sectional view of part of the air conditioning unit 10 in an embodiment of the present invention, figure 2 It is a front view of the air conditioning unit 10 viewed from the vehicle interior side. figure 1 , figure 2 The overall configuration of the shown air conditioning unit 10 may be the same as that in JP-A-2002-307929. Hereinafter, the outline of the air conditioning unit 10 will be described.
[0053] The ventilation system (indoor unit portion) of the vehicle air conditioner in this embodiment can be broadly divided into two parts: the air conditioner unit 10 and the blower unit (not shown). The air blower unit is arranged offset from the central part toward the passenger seat side in the lower part of the instrument panel of the vehicle interior, whereas the air conditioner unit 10 is arranged approximately in the center of the vehicle width (left and right)...

A foot opening portion 27 of a side surface wall portion 11b in a case 11 is made generally sectorial in opening shape. Seal surfaces S1, S2 are formed on a peripheral edge of the generally sectorial opening shape, and a generally sector resinous door base plate 28a moving on the foot opening portion 27, and lip-shaped seal materials 31, 32 provided on an outer peripheral portion of the door base plate 28a are equipped on a foot door 28. The lip-shaped seal materials 31, 32 are integrally molded with the resinous door base plate 28a by a thermoplastic elastomer. The lip-shaped seal materials 31, 32 receive wind pressure in the case 11 and press-contact with seal surfaces S1, S2 for self-sealing. To save cost for a sealing mechanism while ensuring sealing performance.
Description
technical field [0001] The present invention relates to a vehicle air conditioner, in particular to the improvement of the air passage opening and closing mechanism in the vehicle air conditioner. Background technique [0002] Conventionally, in a vehicle air conditioner, it is known to have lower openings on the left and right side wall portions of a housing of a heat exchanger housing an air conditioning unit, and to provide left and right lower doors that move along the left and right side wall portions. The left and right lower doors open and close the left and right lower openings (for example, JP 2002-307929). [0003] According to this prior art, other doors, specifically, front doors, can be arranged with a predetermined gap between the left and right lower doors. That is, the left and right lower doors and the front door can be arranged so that the movement trajectories of the two doors overlap when viewed from the vehicle width direction. Thereby, there is an adv...
