摘要

The arm rest has a cup holder (B) with a local peripheral surface area provided with an even clamping projection (21), and a three-dimensional lining component (A) with an opening (H) having an rotating edge (11). The projection exhibits an outer peripheral wall to expand the opening evenly. The opening is smaller than an outer peripheral wall of the projection. The holder is inserted into the opening, where the rotating edge is expanded evenly through and along the peripheral wall of the projection. A foam pad and the holder are filled in the lining component in an integrated manner.
