PURPOSE: A rear suspension for adjusting lateral rigidity in a vehicle is provided to improve lateral rigidity in suddenly turning or stopping the vehicle by adjusting lateral rigidity through a driver with installing a variable torsion bar in the rear suspension, and to increase travel stability by damping vibration efficiently with the torsion beam and the torsion bar. CONSTITUTION: A rear suspension comprises a U-shaped torsion beam connecting trailing arms(2) combined with rear wheels; a torsion bar(6) placed in the recess of the torsion beam to connect the trailing arms; a variable unit(10) fixed in the center of the torsion beam; and variable torsion bars(81,82) surrounding the outer periphery of the torsion bar and sliding in parallel with the torsion bar. The variable unit is composed of a driving gear(11) and two driven gears(21,22), and the hollow of the driven gear is thread-connected to the outer periphery of the variable torsion bar. The variable torsion bars slide along the torsion bar with rotating two driven gears in rotating the driving gear, and move opposite to each other with forming the thread in one driven gear opposite to the other tread in the other driven gear.
