<p>A vibration isolating apparatus (10) in which a vibrating body (71), which is disposed within a pressure-receiving liquid chamber (34) and is connected to a mounting member such that a gap (84) is formed between an inner wall surface of the pressure-receiving liquid chamber (34) and the vibrating body (71), is disposed. An elongated limiting passage (80) is formed in the vibrating body so as to penetrate therethrough. The limiting passage communicates the pressure-receiving liquid chamber and an auxiliary liquid chamber (64) provided within the mounting member. When there is low-frequency vibration, there is liquid-column resonance of a liquid within the limiting passage. However, because the limiting passage is elongated, the liquid-column resonance of the liquid therein is large, and a high loss factor is obtained. Therefore, the low-frequency vibration is reliably absorbed. When there is high-frequency vibration, there is liquid-column resonance of the liquid in a vicinity of the gap. A dynamic spring constant decreases, and the high-frequency vibration is reliably absorbed. <IMAGE></p> |
