Abstract
Herein disclosed is a damper device which is so constructed that a main sealed chamber is formed between one mounting member and the other mounting member by an elastic rubber member providing connection in between, that an auxiliary sealed chamber is formed at the opposite side of the other mounting member to the main sealed chamber by an elastic cover, that the main sealed chamber and at least a portion of the auxiliary sealed chamber are charged with a liquid, that the main sealed chamber and the auxiliary sealed chamber are partitioned by such a partition as is made movable in the direction jointing the two chambers and as is arranged to have its movable range restricted, and that a slot passage is formed between said partition and a wall surrounding the latter. The aforementioned passage is sized to generate in the liquid in the vicinity thereof not when high-frequency vibrations are applied from the one mounting member in the direction joining the two mounting members but when low-frequency vibrations are applied. The damper device thus constructed has remarkably excellent spring and damping constants.
