PROBLEM TO BE SOLVED: To improve the vibration absorbing function and the arm holding function of a rubber bush for an automobile. SOLUTION: A projection-like stopper (a projecting part) 20 formed as a three-stage structure extends from the axis 31 of a suspension arm 15 connected to the rubber bush 12, and is arranged in two places on the outer periphery of an inner cylinder 13 adjacent onto a line passing through a central point 30 of the inner cylinder 13 of the rubber bush 12. Its constitution is constituted of lower projection parts 22 and 24 adjacent in the front and rear as projection parts 21 and 23 high in the center, and can thereby impart the function for processing a load of the whole rubber bush without performing processing by concentrating in one place to the load applied to the rubber bush 12, so that load processing quantity is improved.
