【発明の効果】以上説明した通り、本発明によれば、以
下に記載する格別の作用効果を有する。As described above, according to the present invention, the following special effects can be obtained.

【００３９】（１）本発明による自動車用内装部品は、
中接部芯材に設けた係止用爪をドアトリム本体の樹脂芯
材内部に埋設固定することにより、トリム本体に対して
中接部材を取付固定するというものであるから、従来の
爪を折曲固定する取付けに比べ、強固な取付けが期待で
きるため、中接部材がぐらついたり、周縁部分とトリム
本体との間にスキが生じたりすることがなく、周縁部分
の見栄えが向上し、かつ強固な一体化が図れるという効
果を有する。(1) The automotive interior parts according to the present invention are:
The locking claw provided on the core of the insulated part is embedded and fixed inside the resin core of the door trim body, so that the insulated member is attached and fixed to the trim body. Stronger mounting can be expected compared to mounting by bending, so there is no wobbling of the insulated member and no gap between the peripheral part and the trim body, and the appearance of the peripheral part is improved and it is strong. This has the effect of achieving high integration.

【００４０】（２）本発明方法によれば、トリム本体の
モールドプレス成形時、中接部材を一体化するというも
のであるから、トリム本体の孔開け加工が廃止できるこ
とにより、製造工程を短縮化できる効果がある。(2) According to the method of the present invention, the inscribed member is integrated at the time of mold press molding of the trim main body, so that the drilling of the trim main body can be eliminated, thereby shortening the manufacturing process. There is an effect that can be done.

【００４１】（３）トリム本体のモールドプレス成形
時、中接部材を同時に一体化するというものであるか
ら、従来のように、成形されたトリム本体に対して中接
部材を爪の折曲加工により取付けるという面倒な取付作
業が廃止できることから、製造工程が大幅に短縮化でき
るという効果を有する。(3) Since the intermediate member is integrated at the same time as the mold press molding of the trim main body, the intermediate member is bent to the formed trim main body and the claws are bent. Since the complicated mounting work of mounting can be eliminated, there is an effect that the manufacturing process can be greatly shortened.
