PROBLEM TO BE SOLVED: To provide a torsion beam type suspension which avoids weight increase in a more reliable manner, eases stress concentration in a joint part between a tray ring arm and a torsion beam, enables easy positioning, and achieves high productivity.SOLUTION: A torsion beam type suspension 2 includes: a long plate-like torsion beam 5 which exhibits an open shape that opens in one direction; and a pair of tray ring arms 6 which are connected with both ends of the torsion beam 5. Each tray ring arm 6 includes a beam joint part 13 which has a hollow structure and is butted to the torsion beam 5 to be joined thereto. |
