To provide a fastening structure for a vehicular air conditioning unit in which, an intermediate case member is arranged between a first case member and a second case member, and the case members are fastened by a fastener for forming an air conditioning case, arrangement and configuration of a flange part provided on each of the first case member and the intermediate case member, and a boss part provided on each of the intermediate case member and the second case member are contrived.SOLUTION: An air conditioning case 11 comprises: a first case member 26; a second case member 27; and an intermediate case member 28. The case members 26, 27, 28 are coupled by inserting a screw shaft part 32 of a first fastener 30 into a first flange part 40 of the first case member 26 and an intermediate boss part 43 of the intermediate case member 28, and inserting a screw shaft part 35 of a second fastener 33 into an intermediate flange part 46 of the intermediate case member 28 and a second boss part 52 of the second case member 27. The screw shaft part 32 of the first fastener 30 can be inserted into a first boss part 49 of the second case member 27.SELECTED DRAWING: Figure 1
【課題】第1ケース部材と第2ケース部材とを、間に中間ケース部材を配置して、締結具により締結することで空調ケースを構成するにあたって、第1ケース部材及び中間ケース部材にそれぞれ設けたフランジ部、中間ケース部材及び第2ケース部材にそれぞれ設けたボス部の配置・構成を工夫した車両用の空調ユニットの締結構造を提供することを目的としている。【解決手段】空調ケース11は、第1ケース部材26、第2ケース部材27、及び中間ケース部材28を有し、ケース部材26、27、28は、第1ケース部材26の第1フランジ部40と中間ケース部材28の中間ボス部43とに第1締結具30のネジ軸部32を挿入し、中間ケース部材28の中間フランジ部46と第2ケース部材27の第2ボス部52とに第2締結具33のネジ軸部35を挿入することにより連結されるようにしつつ、第2ケース部材27の第1ボス部49について第1締結具30のネジ軸部32を挿入可能な構成とする。【選択図】図1
