PROBLEM TO BE SOLVED: To sufficiently absorb rocking of an engine due to cranking vibration or starter antitorque occurring when stopping an engine or when starting the engine.SOLUTION: A vibration control device includes: top surface side basic ribs 22 extending in directions intersecting an axial open end 6a of a cylindrical part 6; back surface side basic ribs 22a opposing to a suspension arm 15; and additional ribs 23 arranged between the back surface side basic rib 22a and the back surface side basic rib 22a and extending in directions intersecting the axial open end 6a. The top surface side basic ribs 22 are formed to have such a protruding length that the tip part thereof is in contact with the axial open end 6a. The back surface side basic ribs 22a are formed to have such a protruding length that the tip part thereof is in contact with the suspension arm 15, and are arranged to overlap with the top surface side basic ribs 22 intersecting the axial open end 6a. The additional ribs 23 are formed to be lower than a height position of the tip parts of the back surface side basic ribs 22a and to have such a protruding length that the additional ribs come into contact with the suspension arm 15 after the back surface side basic ribs 22a deform. |
