PURPOSE: A rear axle assembly structure improves stiffness thereof and driving stability due to low deflection phenomenon. CONSTITUTION: A tortion beam(50) of an 'U' shape opening toward a ground surface along a length thereof comprises a curved member(52) formed by being bent outward the both ends thereof, so that a tortion center of the tortion beam(50) is to be positioned on the upper portion thereof. The tortion beam(50) with the curved member(52) prevents crack phenomenon generated on the end portion of the tortion beam(50) so as to improve stiffness thereof and minimizes tortion degree so as to improve driving stability.
