PROBLEM TO BE SOLVED: To enhance the durability of a vibration isolating apparatus by preventing an elastic film from making contact with the circumference of a through hole. SOLUTION: An intermediate cylinder 22 and an intermediate block 24 are arranged inside an outer cylinder metal fitting 16 an a space partitioned by the intermediate block 24 and an elastic body 28 constitutes a main liquid chamber 30. A shake orifice 64 and an idle orifice 60 communicate the main liquid chamber 30 with a first auxiliary liquid chamber 32. An orifice 62 for confining communicates the main liquid chamber 30 with a second auxiliary liquid chamber 96 and a rotor 36 opens and closes the idle orifice 60 and the orifice 62 for confining. In this case, a second diaphragm 94 constituting a portion of the partition wall of the second auxiliary liquid chamber 96 is provided with a thick-walled part 94B, and a through hole 80 provided in the outer cylinder metal fitting 16 is arranged in an opposite relation to the thick-walled part 94B. |
