PURPOSE: A device for testing endurance of a suspension bush is provided to exactly control a twist angle by supplying twist load and to reduce a noise by simplifying installing structure. CONSTITUTION: An endurance testing device of a suspension bush for a vehicle comprises a fixing apparatus(5) surrounding an outer case(3) of a bush(1); a load apparatus(7) applying load into the bush; a twist loader(9) applying twist load toward a front direction of the bush; left and right blocks(13,15) connected each other by a bolt(11); a piston rod(17) mounted on a side of the fixing apparatus; a hydraulic cylinder(19) moving front and back via the piton rod by being fixed on a support frame(21); and a combining bolt(29) connecting a vertical plate(33) to an inner case(25) of the bush. Thereby, the endurance testing device of the suspension bush for the vehicle exactly control a twist angle by supplying the twist load to reduce noise.
