Abstract
Disclosed is a rubber bushing which includes an inner cylindrical member including irregularities formed on a part of an outer peripheral surface thereof, a ring made of resin, the ring disposed integrally on the outer peripheral surface on which the irregularities are formed, and the ring having an anomalous shape which is formed anomalously in radial directions with respect to a cylindrical axis of the inner cylindrical member, an elastic member made of rubber, the elastic member formed outside the inner cylindrical member, and an outer cylindrical member connected to the inner cylindrical member by way of the elastic member. Thus, the rubber bushing has an enhanced ratio of the spring characteristic in the axial direction with respect to the spring characteristic in the direction perpendicular to the axial direction. The rubber bushing having such an excellent spring characteristic can be mass-produced without increasing the conventional production cost.
