The present invention relates to a roof rail structure for a vehicle, and aims to ensure watertightness between a bolt of a roof rail and a roof of a vehicle body without using a sealing gasket. The roof rail is provided with: a rail body extending in the front-rear direction of the vehicle body; and a leg part which fixes the longitudinal beam main body on the roof panel of the vehicle body. The leg part is provided with: a protector which is in contact with the roof panel; a leg placed on the protector; a coupling portion that couples a bolt protruding from the bottom of the leg through the protector and the roof panel and to the roof panel; and the water stopping part is used for stopping water from flowing to the periphery of the connecting part. The water stop portion includes: a bottom surface sealing rib protruding from the bottom surface of the protector, covering the periphery of the bolt, and abutting against the roof panel; and an upper surface sealing rib which is provided on the upper surface of the protector in a protruding manner, covers the periphery of the bolt, and is in contact with the bottom surface of the leg.

    本发明涉及车辆用车顶纵梁结构,旨在无需使用密封垫片就能确保车顶纵梁的螺栓和车体的车顶之间的止水性。车顶纵梁具有:纵梁主体,其沿着车体的前后方向延伸;支腿部,其将纵梁主体固定设置在车体的车顶板上。支腿部具有:保护件,其与车顶板抵接;支腿,其载置在保护件上;联接部,其使从支腿的底部突出的螺栓贯穿保护件和车顶板并与车顶板联接;止水部,其阻挡水流到联接部的周围。止水部包括:底面密封肋,其突出设置在保护件的底面,覆盖螺栓的周围并与车顶板抵接;上表面密封肋,其突出设置在保护件的上表面,覆盖螺栓的周围并与支腿的底面抵接。
