PROBLEM TO BE SOLVED: To adequately disperse a load added to a tow hook thereby suppressing deformation and breakage of a bumper reinforcement.SOLUTION: A U-shaped fixture 20 is mounted so that an upper wall supported part 21, a front wall supported part 22 and a rear wall supported part 24 are supported by surface contact with an upper wall 11, a front wall 13 and a rear wall 14 of a bumper reinforcement 10 respectively, female screw parts 22a, 24a, which are engaged with a male screw part 42 of a tow hook 40, are formed on the front wall supported part 22 and the rear wall supported part 24 of the fixture 20. Thus, a load added to the tow hook 40 can be received by three faces of the upper wall 11, the front wall 13 and the rear wall 14 of the bumper reinforcement 10, and therefore, concentration of stress is avoided, and deformation and breakage of the bumper reinforcement 10 can be suppressed.SELECTED DRAWING: Figure 3
【課題】牽引フックに加わる荷重を適切に分散させてバンパリインフォースの変形や破損を抑制する。【解決手段】U字状の取付具20を、上壁被支持部21,前壁被支持部22,後壁被支持部24がそれぞれバンパリインフォース10の上壁11,前壁13,後壁14に面接触により支持されるように装着し、牽引フック40の雄ねじ部42に螺合する雌ねじ部22a,24aを、取付具20の前壁被支持部22,後壁被支持部24に形成する。これにより、牽引フック40に加わる荷重をバンパリインフォース10の上壁11と前壁13と後壁14の3面で受けることができるため、応力集中を回避して、バンパリインフォース10の変形や破損を抑制することができる。【選択図】図3
