Abstract
Abstract A doughnut plate type stop member is fixed to an opening edge of a stay hole formed on a skin. A concave groove is provided at a predetermined position of a stay of an insert. The stay extending from a base portion is disposed to protrude outward by inserting through the stay hole upon disposing the base portion of the insert in the skin. The stop member is engaged with the concave groove. Upon securing the foregoing condition, a foamed plastics material is poured into the skin, and a headrest is produced by providing a foamed plastic unit integrating the skin and the insert by means of a foam molding.
