PROBLEM TO BE SOLVED: To unfailingly achieve attenuation characteristics.SOLUTION: In a vibration-proofing device, a swirl chamber unit 33 having a swirl chamber 34 which swirls a liquid flowing thereinto is provided at an idle orifice 22. The swirl chamber unit 33 includes: a rectifying passage 35 which allows the swirl chamber 34 to communicate with a main liquid chamber and opens toward a circumferential direction of the swirl chamber 34 in the swirl chamber 34; and a communication hole 36 which allows the swirl chamber 34 to communicate with a sub liquid chamber. The swirl chamber 34 forms swirl flow of the liquid according to a flow rate of the liquid flowing in from the rectifying passage 35 and causes the liquid to flow out from the communication hole 36. |
