Description

本発明は、車両のバンパ部に形成された開口部を塞ぐ、カバーの取付け構造に関する。 The present invention relates to a cover mounting structure that closes an opening formed in a bumper portion of a vehicle.

車両の故障時等のため、車両には牽引用フックが備えられる。一般には、牽引用フックが備えるネジ部の締結部を車体骨格に配設し、バンパの上記締結部が位置する箇所に開口部を設け、この開口部を覆うカバーが取り付けられる。また、牽引フック用は、レンチ等の工具と同様に車載される。 The vehicle is provided with a tow hook for a vehicle failure or the like. In general, a fastening portion of a screw portion provided in the tow hook is disposed on the vehicle body skeleton, an opening is provided at a position where the fastening portion of the bumper is located, and a cover that covers the opening is attached. The tow hook is mounted on the vehicle in the same manner as a tool such as a wrench.

バンパの開口部にカバーを取付ける構造として、例えば特許文献１ではバンパの開口部にフランジが形成され、カバーにはバンパに形成されたフランジに係合する係合部が、外周方向に左右、及び上下位置に形成され、うち車両下側に位置する係合部には、ヘラ状部材が係合可能な引っ掛り部を有する、カバー取付け部の構造が開示されている。 As a structure for attaching the cover to the opening of the bumper, for example, in Patent Document 1, a flange is formed in the opening of the bumper. The structure of the cover attachment part which has a hook part which can be engaged with a spatula-like member is disclosed in the engaging part which is formed in the vertical position and is located on the vehicle lower side.

しかしながら、特許文献１の取付け構造においては、カバー取外し時にバンパやカバーに傷をつけることは防止されるが、係合部がカバーの外周に４箇所形成される。このためカバーを製造する型の構造が複雑となりコスト増加の原因となる。また、引っ掛り部が形成された１箇所の係合部以外に３箇所の係合を外す必要が生じ、作業性が低下するという問題が残る。 However, in the mounting structure of Patent Document 1, it is possible to prevent the bumper and the cover from being damaged when the cover is removed, but four engaging portions are formed on the outer periphery of the cover. For this reason, the structure of the mold for manufacturing the cover is complicated, which causes an increase in cost. Moreover, it becomes necessary to disengage three places other than the one engaging part in which the hook part was formed, and the problem that workability | operativity falls remains.
