To make compatible the durability of resilient members 30a, 30b, 30c and 30d and the vibration isolation performance of a compressor 10 with each other.SOLUTION: A support member 40 supporting a compressor 10 via resilient members 30a, 30b, 30c and 30d is installed in a vehicle body 20. The resilient members 30a, 30b, 30c and 30d are arranged between leg portions 40a, 40b, 40c and 40d of the support member 40 and the compressor 10. The resilient members 30a, 30b, 30c and 30d suppress the propagation of vibration from the compressor 10 to the vehicle body 20 via the leg portions 40a, 40b, 40c and 40d of the support member 40. In order to make compatible the durability of the resilient members 30a, 30b, 30c and 30d and vibration isolation performance with each other when the compressor 10 vibrates at a six-degree of freedom, the compressor 10 and the resilient members 30a, 30b, 30c and 30d are set so as to make six resonance frequencies generated at the compressor 10 match one prescribed frequency.SELECTED DRAWING: Figure 1

    【課題】弾性部材30a、30b、30c、30dの耐久性とコンプレッサ10の防振の性能とを両立させる。【解決手段】車体20には、弾性部材30a、30b、30c、30dを介してコンプレッサ10を支える支持部材40が設置されている。弾性部材30a、30b、30c、30dは、支持部材40の脚部40a、40b、40c、40dおよびコンプレッサ10の間に配置されている。弾性部材30a、30b、30c、30dは、コンプレッサ10からの振動が支持部材40の脚部40a、40b、40c、40dを介して車体20に伝わることを弾性変形によって抑制する。コンプレッサ10が6自由度で振動した際に、弾性部材30a、30b、30c、30dの耐久性と防振の性能とを両立させるために、コンプレッサ10に生じる6つの共振周波数を1つの所定周波数に一致させるようにコンプレッサ10および弾性部材30a、30b、30c、30dが設定されている。【選択図】図1
