Component part mounting structure

A method for mounting a component part onto a surface of a vehicle upholstery member by using a self-tapping screw, wherein the upholstery member comprises a base portion projecting from a rear surface of the upholstery member and defining a space in cooperation with the rear surface, and a boss portion projecting from the base portion and defining a hole opening out toward the space, and the component part is provided with a fastening seat abutting the front surface of the upholstery member and having a through hole passed across the fastening seat, the method comprising the steps of:

• forming a hole in the upholstery member by passing the self-tapping screw from the side of the component part through the through hole of the fastening seat and into the upholstery member;
• removing the self-tapping screw from the component part and upholstery member, and inspecting if axial centers of the through hole of the component part and the hole of the boss portion align with each other;
• if the two axial centers of the through hole of the component part and the hole of the boss portion do not align with each other, adjusting the position of the component part with respect to the upholstery member so as to align the two axial centers of the through hole of the component part and the hole of the boss portion with each other;
• and
• threading the self-tapping screw through the through hole of the component part and into the hole of the boss portion with the two axial centers of the through hole of the component part and the hole of the boss portion aligned with each other.
