全てのカバー構成体２１がスチールホイール１０に螺子止めされたら、ホイールカバー２０が固定されたスチールホイール１０を車両（図示せず）に取り付ける。具体的には、車両に備えたハブ盤３０（図４参照）にハブ取付部１２の内面を宛がい、ハブ盤３０から突出したハブボルト３１をハブ取付部１２における各ハブボルト挿通孔１６に突入させる。そして、それらハブボルト３１の先端にナットＮを締め付けてスチールホイール１０をハブ盤３０に固定する。このとき、ナットＮとハブ取付部１２との間にカバー構成体２１の共締壁２５が挟持される。これにより、カバー構成体２１がスチールホイール１０に固定され、ホイールカバー２０のスチールホイール１０に対する取り付けが完了する。   When all the cover components 21 are screwed to the steel wheel 10, the steel wheel 10 to which the wheel cover 20 is fixed is attached to a vehicle (not shown). Specifically, the inner surface of the hub mounting portion 12 is applied to the hub board 30 (see FIG. 4) provided in the vehicle, and the hub bolts 31 protruding from the hub board 30 are inserted into the hub bolt insertion holes 16 in the hub mounting section 12. . And the nut N is fastened to the front-end | tip of these hub bolts 31, and the steel wheel 10 is fixed to the hub board 30. FIG. At this time, the fastening wall 25 of the cover structure 21 is sandwiched between the nut N and the hub mounting portion 12. Thereby, the cover structure 21 is fixed to the steel wheel 10, and the attachment of the wheel cover 20 to the steel wheel 10 is completed.

ホイールカバー２０がスチールホイール１０に取り付けられると、溝型構造のカバー構成体２１内にスポーク部１３が収まり、カバー構成体２１自体をアルミホイールのスポーク部のように見せることができる。そして、スチールホイール１０のうち露出したリム１１に、ホイールカバー２０のカバー構成体２１が一体に連続した外観を奏する。また、スチールホイール１０のハブ取付部１２においては、ナットＮの側方を覆う湾曲形状のナット受容部２４をカバー構成体２１の端部に設けたことで、カバー構成体２１の端部とハブ取付部１２との境界が判別し難くなり、カバー構成体２１とハブ取付部１２とを一体的に見せることができる。また、共締壁２５をナット受容部２４の奥側に配置したことで、共締壁２５が保護されかつ見え難くなる。さらに、ハブ取付部１２の中心部に固定可能な中心キャップ２８を備え、中心キャップ２８に形成された側面凹部２８Ａに、各カバー構成体２１の端部を受容したことで、意匠上の審美性が向上する。   When the wheel cover 20 is attached to the steel wheel 10, the spoke part 13 is accommodated in the cover structure 21 having a groove structure, and the cover structure 21 itself can be seen as a spoke part of an aluminum wheel. Then, the exposed rim 11 of the steel wheel 10 has an appearance in which the cover component 21 of the wheel cover 20 is integrally continuous. Further, in the hub mounting portion 12 of the steel wheel 10, a curved nut receiving portion 24 that covers the side of the nut N is provided at the end portion of the cover constituent body 21, so that the end portion of the cover constituent body 21 and the hub are provided. It becomes difficult to distinguish the boundary with the mounting portion 12, and the cover structure 21 and the hub mounting portion 12 can be seen integrally. Further, since the co-clamping wall 25 is arranged on the back side of the nut receiving portion 24, the co-clamping wall 25 is protected and difficult to see. Furthermore, the center cap 28 which can be fixed to the center part of the hub attaching part 12 is provided, and the end part of each cover structure 21 is received in the side surface recessed part 28A formed in the center cap 28. Will improve.

このように本実施形態のホイールカバー２０では、スチールホイール１０の各スポーク部１３を覆う複数のカバー構成体２１が、それらスポーク部１３毎の別部品になっているので、従来のホイールカバーのような円盤構造から脱却し、意匠上の自由度が高くなると共に、外観上、ホイールカバー２０をスチールホイール１０に被せた感が抑えられる。これにより、従来より、ホイールカバー２０とスチールホイール１０とが外観上、一体的となり、スチールホイール１０をアルミホイールのように見せることが可能になる。また、ハブ取付部１２の中心部に中心キャップ２８を固定したことにより、スチールホイールを、より一層、アルミホイールのように見せることが可能になる。   Thus, in the wheel cover 20 of this embodiment, since the several cover structure 21 which covers each spoke part 13 of the steel wheel 10 is another component for each of these spoke parts 13, it is like a conventional wheel cover. As a result, the degree of freedom in design increases, and the appearance of the wheel cover 20 covering the steel wheel 10 can be suppressed. Thereby, conventionally, the wheel cover 20 and the steel wheel 10 are integrated in appearance, and the steel wheel 10 can be made to look like an aluminum wheel. Further, by fixing the center cap 28 at the center of the hub mounting portion 12, the steel wheel can be made to look more like an aluminum wheel.

しかも、本実施形態のホイールカバー２０によれば、スチールホイール１０に取り付ける前の状態では、複数のカバー構成体２１を重ねて一纏めにすることでコンパクトになる。その上、ホイールカバー２０を成形するための樹脂成形用金型においては、カバー構成体２１を成形するための成形部の数及び配置を自由に決定することができるので、従来の円盤構造のホイールカバー用の樹脂成形金型に比べて、設計の自由度が高くなり、必要に応じて樹脂成形用金型を小型にしたり、金型制作費を抑えることができる。   Moreover, according to the wheel cover 20 of the present embodiment, in a state before being attached to the steel wheel 10, the plurality of cover constituent bodies 21 are stacked to be made compact. In addition, in the resin molding die for molding the wheel cover 20, the number and arrangement of molding parts for molding the cover structure 21 can be freely determined. Compared to the resin molding die for the cover, the degree of freedom of design is higher, and the resin molding die can be made smaller or the mold production cost can be reduced as necessary.
