PROBLEM TO BE SOLVED: To reduce the transmission of vibrations accompanied with coolant passing, while suppressing the increase of weight, in a vehicular air conditioner 1.SOLUTION: A vehicular air conditioner 1 is equipped with an expansion valve 52; an air conditioning case 11; a heat exchanger 20 for cooling disposed in the air conditioning case 11; a coolant pipe 90 connecting a coolant outlet of the expansion valve 52 and a coolant inlet of the heat exchanger 20 for cooling; and a packing 100 formed by an elastic member, and disposed between the coolant pipe 90 and the air conditioning case 11 in the air conditioning case 11. The packing 100 suppresses the transmission of vibrations from the coolant pipe 90 to the air conditioning case side, while pressed by a plurality of ribs 110 of the air conditioning case 11 and elastically deformed between the air conditioning case 11 and the coolant pipe 90. 【課題】車両用空調装置１において、重量の増加を押さえつつ、冷媒通過に伴う振動が乗員側に伝わることを低減する。【解決手段】 車両用空調装置１は、膨張弁５２と、空調ケース１１と、空調ケース１１内に配置されている冷却用熱交換器２０と、膨張弁５２の冷媒出口と冷却用熱交換器２０の冷媒入口を接続する冷媒配管９０と弾性部材により形成されて空調ケース１１内にて冷媒配管９０および空調ケース１１との間に配置されているパッキン１００とを備え、パッキン１００は、空調ケース１１の複数のリブ１１０によって押さえられて空調ケース１１および冷媒配管９０の間で弾性変形した状態で、冷媒配管９０からの振動を空調ケース側に伝えることを抑制する。【選択図】図５
