Description

  The present invention relates to a vehicle body outer plate reinforcing member capable of improving the surface rigidity of a vehicle body outer plate of a vehicle such as an automobile, and a vehicle door including the vehicle body outer plate reinforcing member.

  In recent years, for the purpose of reducing carbon dioxide emissions by improving fuel economy, there has been a demand for weight reduction of vehicles such as automobiles, and in front side doors and rear side doors made of thin steel sheets such as cold rolled steel sheets for automobiles, There is a demand to make the thickness of the outer plate of the vehicle body as thin as possible.

  If the body thickness of the front side door and rear side door is reduced as much as possible to reduce weight, the surface rigidity (also referred to as “tension rigidity”) of the body outer plate will be reduced and pressed by hand. There was a possibility that the outer plate of the vehicle body would be bent by external force.

  In order to satisfy the conflicting demands of weight reduction and surface rigidity at the same time, as shown in Patent Document 1 and Patent Document 2, for example, the vehicle interior side of the vehicle body skin of the front side door and the rear side door is shown. In addition, it is a common practice to bond a plurality of reinforcement members (reinforcement) with a soft adhesive called a mastic sealer to improve the surface strength of the vehicle body outer plate.
