Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、自動車の外板側面等に取り付ける。[Detailed description of the invention] [Industrial application field] The present invention is attached to the side surface of an outer panel of an automobile.
位置決め具を具備したモールの製造方法に関する。The present invention relates to a method of manufacturing a molding equipped with a positioning tool.
自動車の車体側面には、装飾性と車体保護を兼ねてモー

該モールは、主として半硬質ないし軟質のポリプロピレ

着テープ92により。As shown in FIG. 11, conventional moldings include a molding 91 made entirely of synthetic resin;
Some are made of a double-sided adhesive tape 92 attached to the back side of the molding 91. This molding 91 is made with double-sided adhesive tape 92.
車体に貼着して取り付ける。Attach to the vehicle body.

94も提案されている(例えば、特開昭61−1432
40号公報)。Furthermore, as shown in FIG. 12, there is also one in which a clip 931 as a positioning tool is integrally molded at the same time as the molding body 93. Furthermore, as shown in FIG. 13, a molding 94 in which bolts 95 as one positioning tool are fixed at predetermined positions has also been proposed (for example, Japanese Patent Laid-Open No. 61-1432
Publication No. 40).
該ボルト95は、その基板951をモールの裏面に樹脂

(7 to 12 trout/-300 to 80 degrees Celsius), therefore, due to this expansion and contraction, the molding may bend in the summer and come off the vehicle body in the winter. Furthermore, a gap is created between the end of the molding and the end of the vehicle body due to expansion and contraction, and for example, a gap is created between the end of the door and the end of the molding, resulting in poor appearance.
また、前記両面接着テープを用いたモールは。In addition, there is a molding using the double-sided adhesive tape.
特定の位置決め部分がないため、これを車体に貼着する
ときには作業者のカンによる位置決めが要求される。Since there is no specific positioning part, when attaching this to the vehicle body, the operator is required to position it using a ring.
