PURPOSE:To decrease the number of part items, to simplify manufacture and reduce the cost and weight thereof. CONSTITUTION:A vibration control device is wholly integrally formed with a resin material. In upper and lower end parts 11, 13 made of substantially rigid material, connecting fittings 21, 22 respectively connected to an engine and a vehicle frame are embedded. An intermediate part 12 is formed in a thin elliptical shape. Both circular arc end parts can be elastically deformed at a specified spring constant. Vibration input to the upper end part 11 is absorbed by the elastically deformed intermediate part 12 and is not transmitted to the lower end part 13. An entire body is integrally formed out of a resin material, so that the number of part items is decreased, manufacture is simplified and performed at a low cost and low in weight because of the small number of metal parts. |
