Abstract: A void bush for a vehicle suspension includes: inside bumps formed in an inside stopper and outside bumps formed in an outside stopper. In particular, the inside bumps and the outside bumps are configured to cross perpendicularly to each other to allow the inside bumps and the outside bumps to be brought into point-contact with each other during behavior of the suspension. The inside bumps are not arranged in parallel to each other and the outside bumps are not arranged in parallel to each other. Accordingly, contact area between the inside bumps and the outside bumps is greatly reduced and contact abrasion positions therebetween are diversified so that durability and lifespan of the void bush are improved.
