PURPOSE:To improve the durability of a device by preventing interference between an elastic body and a bracket when the elastic body such as rubber is considerably deflected, in the case of said device arranged between a power unit and a car body. CONSTITUTION:An insulator 130 is constituted by an inside part 131 supported by an inner cylinder 110, an outside part 132 supported by an outer cylinder 120 and provided with a prescribed amount of gap delta against the inside part 131, and connecting parts 133, 133 for connecting together these inside and outside parts 131, 132. When a power unit is considerably displaced, the inside part 131 and outside part 132 of the insulator 130 make close contact with each other to restrict the displacement of the power unit, but the connecting parts 133, 133 are respectively deformed in the perpendicular direction with respect to the center axis of the inner cylinder 110. Namely, these connecting parts 133, 133 are deformed approximately in parallel to and along brackets 161, 161, thus preventing their interference with the brackets 161, 161. |
