Abstract

An anti-vibration device according to the present invention makes it possible to achieve compactness and sufficient durability without increasing the number of parts. To be specific, an anti-vibration member 10 is made up of an inner cylinder 4, an outer ring 6, and a rubber-like elastic body 8. The outer ring 6 is disposed outside the inner cylinder 4. The outer ring 6 is attached to a frame-side member 5. An end plate 7 is provided at an outer end portion of the inner cylinder 4. The rubber-like elastic body 8 is disposed between the inner cylinder 4, the outer ring 6, and the end plate 7. The anti-vibration rubber assembly 10 is provided on each side of the frame-side member 5. A guide member 9 is interposed between the two inner cylinders 4 and is unified therewith. The inner cylinder 4 is attached to an engine-side bracket 3. The guide member 9 faces the outer ring 6 in the radial direction and guides the inner cylinder 4 in the up-and-down direction. Damage of the rubber-like elastic body 8 due to displacement in the horizontal direction is prevented while an engine 2 is elastically supported thereby suppressing vibration.
