A torsion beam suspension capable of preventing a rapid change in rigidity at a connection portion between a trailing arm and a torsion beam is provided.;The present invention is a torsion beam suspension 100 including an upper member 10 and a lower member 20, and including right and left trailing arms 50 configured to include a pair of trailing arm configuration members 11 and the pair of lower members and configured to extend in a longitudinal, direction of a vehicle body and to be swingable in a vertical direction and a torsion beam 16 which is disposed between the right and left trailing arm configuration members the upper member 10. The lower member includes an upper connection 21 and a beam joint portion 22 inclined from the upper connection 21 to a bottom portion of the U-shaped cross section of the torsion beam and joined with the torsion beam. |
