An aluminum member exhibits improved alkali resistance with respect to an anodic oxide coating. The highly alkali-resistant aluminum member includes a material that includes aluminum or an aluminum alloy, an anodic oxide coating that is formed on the surface of the material, and a coating layer that is formed on the anodic oxide coating, and includes a siloxane glass component in a ratio of 90 mass % or more, wherein the coating layer has a thickness of 0.5 to 5.0 &#x3bc;m and a coating mass of 0.4 to 5.0 g/m.

Highly alkali-resistant aluminum member

A ramp apparatus for a vehicle includes a ramp retractable in the vehicle and drawable to an outside of the vehicle, a moving body movable in a drawing direction and a retracting direction together with the ramp, a support arm rotatably coupled with the ramp at a first rotatable coupling point and rotatably coupled with the moving body at a second rotatable coupling point, and a tension spring interposed between the ramp and the moving body. The ramp is arranged in a lifted-up position in which the ramp faces a door opening of the vehicle from a drawn position. The tension spring rotationally urges the first rotatable coupling point positioning above the tension spring in the drawn position of the ramp about the second rotatable coupling point and exerts an urging force on the ramp, the urging force moving the ramp from the drawn position toward the lifted-up position.

Ramp apparatus for vehicle

An impact absorbing device includes an impact absorbing member extending in a vehicle front-rear direction; and a bumper reinforcement that extends in a vehicle width direction and is attached to a front end surface of the impact absorbing member. The bumper reinforcement includes a body portion extending in the vehicle width direction and having a length in a vehicle height direction that is smaller than a length of the impact absorbing member in the vehicle height direction, and a reinforcing portion fixed to the body portion and extending along a portion of the front end surface of the impact absorbing member, the portion being positioned above or below the body portion.

Impact absorbing device and bumper reinforcement

A towing hook attachment structure includes: a towing hook; a bumper reinforcement having: a first wall extending in a vehicle width direction, a wall surface of the first wall facing the vehicle cabin; and an second wall and a third wall respectively extending to the vehicle cabin side from an upper end and a lower end of the first wall; and a nut member fastening the towing hook to the bumper reinforcement. The first, second and third walls are respectively provided with a first, second and third holes. The nut member is fixed to the bumper reinforcement while extending in a vehicle height direction and being inserted in the second hole and the third hole. A tip of the towing hook is inserted in the bumper reinforcement through the through hole and is fastened to the nut member.
