Therefore, each of the two vibration absorbing members 4a and 4b receives a load in the radial direction instead of the load in the thickness direction. For example, when a compressive load is applied to the vibration absorbing members 4a and 4b in the thickness direction, the amount of compressive deformation in the thickness direction is small, so there is a limit to vibration absorption.

For example, simply stacking two vibration absorbing members 4a and 4b and placing the compressor 100 on top of them will reduce the vibration absorbing effect.

Therefore, the load of the compressor 100 can be effectively dispersed and transmitted to the vibration absorbing members 4a and 4b.

Le support est pourvu d'une plaque d'installation et d'une plaque de support qui se dresse verticalement dans une direction croisant une surface de la plaque d'installation et qui a un premier trou traversant. Les deux éléments d'absorption de vibrations sont chacun disposés dans une position dans laquelle le premier trou traversant est formé et ont des seconds trous traversants en communication avec le premier trou traversant. Les deux éléments d'absorption de vibrations sont disposés de chaque côté de la plaque de support de façon à enserrer la plaque de support. Les deux parties d'attache sont chacune disposées à l'opposé de la plaque de support par rapport à un élément d'absorption de vibrations respectif. Les deux parties d'attache enserrent la plaque de support et les deux éléments d'absorption de vibrations. La partie de fixation passe à travers le premier trou traversant et les seconds trous traversants et fixe les deux parties d'attache. Un élément homologue est attaché à moins l'une des deux parties d'attache.
