Description

  The present invention relates to a vehicle side step provided below a side door of a vehicle such as a passenger car.

For example, a side step is provided below a side door of a passenger car such as a minivan or an SUV (Sports Utility Vehicle) as a step when a passenger gets on and off. As this side step, as an option or the like, it is separately attached to a completed vehicle.
Therefore, in a structure in which the outer side of the metal rocker panel located below the side door is covered with a rocker molding, a side step formed separately from the rocker molding is attached later.

Therefore, in order to prevent a gap from being formed between the rocker molding and the side step, a rubber edge molding may be provided between the vehicle inner end portion of the side step and the outer surface of the rocker molding. Has been done.
However, when this edge molding is provided, not only the number of parts increases, but also the gap between the rocker molding and the side step needs to be adjusted appropriately. In addition, the use of the edge molding not only deteriorates the appearance, but also may cause abnormal noise while the passenger car is running.

In the side step for automobiles of Patent Document 1, the side step is composed of a base portion having a recessed storage space, and a lid-shaped step portion that can be opened and closed with respect to the opening of the storage space of the base portion. Configuration is disclosed.
Further, in the vehicle step structure of Patent Document 2, it is disclosed that a step plate is formed of an aluminum material, and a resin cover including two members is provided around the step plate.

However, in patent document 1, the step part is closed with respect to the opening part of the storage space of a base part by using a hinge part as a fulcrum. Therefore, not only the appearance of the hinge part is bad, but also water or the like may enter the storage space of the base part from the hinge part.
In Patent Document 2, the step plate is sandwiched from both sides by two resin covers. Therefore, it is not sufficient for improving the assembly of the side steps.

Japanese Patent Laid-Open No. 10-230792 JP-A-11-310083

  The present invention has been made in view of such conventional problems, and it is intended to provide a vehicle side step capable of preventing the generation of abnormal noise and intrusion of water and the like, and improving the appearance and assemblability. It is what.

An engaging claw portion 311 is provided for engaging with the. Thereby, as shown in FIG. 4, the step lid portion 3 engages the engaging claw portion 311 with the peripheral portion 231 of the vehicle inner side W <b> 1 of the engagement hole 23, and the step lid portion with the engaging claw portion 311 as a fulcrum. 3 can be attached to the upper surface of the side step constituting portion 22 of the molding body 2 by rotating the vehicle outer end 302 downward. Therefore, the assembly of the step lid 3 is easy.

Further, when the step lid 3 is assembled to the molding main body 2, the bent tip 321 of the inner bent portion 32 of the step lid 3 is disposed so as to face the upper surface 251 of the recess 25 in the molding main body 2 from below. . Accordingly, it is possible to prevent water or the like from entering the side step constituting portion 22 without using a rubber edge molding or the like at the bent tip portion 321 of the step lid portion 3.
Moreover, the inner side bent part 32 of the step cover part 3 has the shape bent upwards. When the step lid 3 is assembled to the molding body 2, the gap between the bent tip 321 of the inner bending part 32 and the rocker molding component 21 of the molding body 2 is inconspicuous and has an excellent appearance. Can be presented.

  Therefore, according to the vehicle side step 1 of this example, it is possible to prevent the generation of abnormal noise and the intrusion of water and the like, and improve the appearance and the assemblability.
