Zusammenfassung:	PURPOSE:To obtain titled article with improved handling ability and functionality taking advantage of the shape recovery characteristics of the alloy to be incorporated, by carrying out a molding of a plastic material filled with a shape memory alloy filler to be subjected to shape memory treatment in the molding. CONSTITUTION:A shape memory alloy filler (pref. Ti-Ni alloy heat-treated at 1,000 deg.C for 20min.) 11 is kneaded with a plastic material 2 to mold a pull-stop piece 3. Before falling in the temperature during said molding, the piece 3 is deformed in such a manner as to broaden downward to perform a shape memory treatment of the filler 11. Subsequently, the piece 3 is deformed to represent such a shape as to be easy to handle, being inserted into the hole of a container 4 followed by heat treatment (pref. at 80 deg.C), effecting shape recovery, thus showing pull-stop performance. EFFECT:Easy to manufacture, thus capable of contriving to reduce the manufacturing man-hours.
