[0001]

The present invention relates to a method for manufacturing an armrest and an armrest structure thereof.

[0002]

2. Description of the Related Art As a conventional armrest structure, for example, as shown in FIGS. 14 to 17, a door panel 3 is provided with a door trim 1 made of a material such as polypropylene.
The armrest 40 is fixed. The armrest 40 is made of a core material 41 made of a material such as polypropylene.
And a skin material 42 made of a material such as TPO or polyvinyl chloride which covers the core material 41.
Is placed in a molding die (not shown) of the skin material 42 and formed at the same time. The core member 41 includes a front fixed portion 43 that can be fixed to the door panel 3 and a grip portion 44 that can be gripped by an occupant (not shown), and an armrest portion 45 that is formed to be substantially the same as the upper surface of the fixed portion 43. And the door panel 3
And a rear-side fixed portion 46 that can be fixed to the rear side. The grip portion 44 is formed with a rib 47 so as to withstand a tensile load by an occupant (see Japanese Utility Model Laid-Open No. 6-8068 as a similar technique).

[0003]

However, in such a conventional armrest structure, the skin material 42 is made of TP.
