According to the present invention, a tubular type torsion beam is manufactured by bending, welding, and coupling a plate material. The plate material has a plurality of protrusions disposed on both side surfaces in a width direction of the vehicle. The torsion beam is manufactured by molding the plate material in a pipe shape by bending the plate material in the width direction and molding the plate material to dispose the protrusions to be in contact with each other to form a gap between the side surfaces of the plate material and then welding and coupling the side surfaces of the plate material.
본 발명에 의한 튜블러 타입 토션빔은, 판재를 절곡시켜 용접 결합하여 제조된 튜블러 타입 토션빔으로서, 상기 판재는, 폭 방향 양측면에 각각 복수 개의 돌기부가 형성되고, 상기 토션빔은, 상기 판재를 폭 방향으로 절곡시켜 파이프 형상으로 성형하되, 복수 개의 상기 돌기부들이 서로 맞닿도록 성형하여 상기 판재의 양측면 사이에 틈새를 형성시킨 후, 상기 판재의 양측면을 용접 결합시켜 제조되는 것을 특징으로 한다.
