The present invention relates to a vehicle side member which doubles energy absorption capacity by inducing a stable crushed shape to sufficiently absorb collision energy in case of front or rear collisions. The vehicle side member comprises: a tubular shaped main body unit extended in a longitudinal direction of a vehicle body and has a double octagonal cross-section shape; and a first reinforcement member disposed crossing the inner space of the main body unit. The thickness of the main body unit can be changed in a longitudinal direction of the vehicle body.

    본 발명은 안정적인 압궤 형상 유도를 통한 에너지 흡수능을 배가시켜, 예를 들어 전방 또는 후방 충돌시 충돌 에너지를 충분히 흡수할 수 있는 차량용 사이드멤버에 관한 것으로, 차체의 길이방향으로 연장하고 2중의 팔각 단면 형상을 가진 관형상의 본체부; 및 상기 본체부의 내부 공간을 가로질러 배치된 제1 보강부재를 포함하고, 상기 본체부는 차체의 길이방향으로 두께가 변화될 수 있다.
