A torsion bar assembling structure in a CTBA(Coupled Torsion Beam Axle) is provided to reduce development costs of a vehicle by easily assembling and disassembling a torsion bar to/from a trailing arm. A structure for assembling a torsion bar in a CTBA comprises a case(3), a chuck(7), an elastic member, a spring, and a cancellation button(15). The case penetrated through a trailing arm(1) has a flange protruded toward the center. The chuck has claws(5) divided into plural sectors for extension of the inner diameter inside the case. The elastic member is placed between the chuck and the case to surround the claws in the chuck. The spring supports the claws of the chuck toward the outer side of the trailing arm. The cancellation button consists of a projection part, a cancellation part, and a press part. The projection part capable of sliding along the case is in contact with the flange of the case not to be separated from the case. The cancellation part of a cone type, which is protruded on the projection part, has an end inserted into the center of the claws in the chuck. The press part penetrates the flange to protrude out of the case. |
