As shown in FIG. 1, the component mounting structure 1 of the present invention includes a U-shaped clamp 10 (an example of a mounted component) that holds and holds a plurality of cables 2, pipes (not shown), and the like. A cylindrical cover 20 (an example of a mounting part) that is made of a synthetic resin and has moderate hardness and flexibility and that is half-opened by the split groove 21 to cover the clamp 10, and for fixing the cover 20 to the clamp 10 The fastener 30 is comprised. Projections 11 are integrally formed on the outer peripheral surface of the clamp 10, and are arranged at three locations along the outer peripheral circle of the clamp 10. On the other hand, the cover 20 is provided with the same number of through holes 22 as the projections 11, and the cover 20 is covered so that the projections 11 are inserted through the through holes 22. In this state, the clamp 10 and the cover 20 are fixed by engaging the fastener 30 with the protrusion 11.

図２に示すように、前記クランプ１０の外周面には円柱の台座１２が一体成形されており、ここに前記突起部１１が立設するように一体成形されている。また、この突起部１１においては、その外周面に勾配のついた補強リブ１３が一体成形されており、先端には大径の頭部１４が一体成形されている。   As shown in FIG. 2, a cylindrical pedestal 12 is integrally formed on the outer peripheral surface of the clamp 10, and the protrusion 11 is integrally formed so as to stand upright here. In addition, the protrusion 11 is integrally formed with a reinforcing rib 13 having a gradient on the outer peripheral surface thereof, and a large-diameter head 14 is integrally formed at the tip.

図２及び図３に示すように、前記留め具３０は、合成樹脂製であり、軸部３１と、この軸部３１の後端に一体成形されるフランジ部３３とから成る。この軸部３１は、軸線に沿って延びる軸孔３２を有しており、この軸孔３２に前記クランプ１０の突起部１１を挿通するように構成されている。また、軸部３１は、軸孔３２の内部に成形される係合爪３４（係合部の一例）を有している。この係合爪３４は、軸孔３２の先端開口部３２ａから内部へ延びて、フランジ部３３の位置する方向へ向かうにつれて中心方向に傾斜するテーパー状を成している。また、この係合爪３４は、複数成形されており、軸孔３２に突起部１１を挿入したとき、当該突起部１１の頭部１４に押されて拡径するように構成されている。   As shown in FIGS. 2 and 3, the fastener 30 is made of synthetic resin, and includes a shaft portion 31 and a flange portion 33 that is integrally formed at the rear end of the shaft portion 31. The shaft portion 31 has a shaft hole 32 extending along the axis, and the projection portion 11 of the clamp 10 is inserted into the shaft hole 32. The shaft portion 31 has an engaging claw 34 (an example of an engaging portion) that is molded inside the shaft hole 32. The engaging claw 34 extends inward from the tip opening 32 a of the shaft hole 32, and has a tapered shape that inclines in the central direction toward the direction in which the flange portion 33 is located. A plurality of the engaging claws 34 are formed, and when the protruding portion 11 is inserted into the shaft hole 32, the engaging claw 34 is pushed by the head portion 14 of the protruding portion 11 so as to expand its diameter.

図２に示すように、クランプ１０にカバー２０を固定するには、クランプ１０にカバー２０を被覆した状態で、留め具３０の軸孔３２にクランプ１０の突起部１１を頭部１４から挿入する。そうすると、突起部１１の頭部１４が係合爪３４を押し拡げながら最終的に係合爪３４の先端から露出する。このため、係合爪３４の先端が頭部１４の座面に引っ掛かかるとともに、留め具３０のフランジ部３３の座面がカバー２０の表面を押さえつけるので、クランプ１０とカバー２０が固定される。   As shown in FIG. 2, in order to fix the cover 20 to the clamp 10, the protrusion 11 of the clamp 10 is inserted from the head 14 into the shaft hole 32 of the fastener 30 in a state where the cover 20 is covered with the clamp 10. . Then, the head portion 14 of the protrusion 11 is finally exposed from the tip of the engaging claw 34 while expanding the engaging claw 34.

上記部品の取付構造１は、留め具３０の軸孔３２にクランプ１０の突起部１１を挿入するだけで、簡単にクランプ１０とカバー２０とを固定できる。また、留め具３０の係合爪３４がテーパ状を成しているので突起部１１をスムーズに挿入することができる。さらに、係合爪３４は、分割するようにして複数成形されているので撓みやすく、突起部１１の挿入性が益々向上する。しかも、クランプ１０とカバー２０とを留め具３０を介して固定しているので、結合強度に優れており、カバー２０を取り外そうと外力が加わっても簡単に外れることなく、破損しない構造になっている。   The above component mounting structure 1 can simply fix the clamp 10 and the cover 20 simply by inserting the projection 11 of the clamp 10 into the shaft hole 32 of the fastener 30. Further, since the engaging claw 34 of the fastener 30 is tapered, the protruding portion 11 can be inserted smoothly. Further, since the engaging claws 34 are formed in a plurality of parts so as to be divided, the engaging claws 34 are easily bent, and the insertion property of the protrusions 11 is further improved. In addition, since the clamp 10 and the cover 20 are fixed via the fasteners 30, the coupling strength is excellent, and even if an external force is applied to remove the cover 20, the structure does not easily come off and is not damaged. It has become.
