PURPOSE: A rear suspension for a bus is provided to hold force applied on an axle and driving and braking torque by integrating and installing a rigid part and a flexible part at a lower radius rod in an X shape. CONSTITUTION: A lower radius rod(10) combines with both vehicle wheels under an axle for transmitting driving force by connecting the vehicle wheels. One end of the lower radius rod is joined with a pair of support beams(1) on which an air spring is placed and the other end is combined with an outrigger frame(2) connected with a lower part of a rear frame forming a rear vehicle body. The lower radius rod is composed of a rigid part(11) forming the central portion and having strong durability against torsion or deformation in receiving external force and flexible parts(12,13) widened from the rigid part, formed like an X, and combined with the support beam and the outrigger frame, respectively. The flexible parts are twisted or deformed to absorb the external force in receiving the external force.
