PROBLEM TO BE SOLVED: To provide a method of joining a bumper member capable of simply caulking a bumper stay and a bumper reinforcement by reducing a cost, without being restricted in its shape or material.SOLUTION: In a method of joining bumper materials, a bumper reinforcement 10 having a rear inclined wall 14 provided with a hole portion 16, and a hollow bumper stay 20 are prepared. The bumper stay 20 is inserted in the hole portion 16 of the bumper reinforcement 10 to penetrate the rear inclined wall 14. A rubber 30 is inserted in the inside of the bumper stay 20, and the rubber 30 is compressed in an axis L direction of the bumper stay 20 to be expanded from the inside toward the outside, thereby expanding and deforming at least a part inserted in the hole portion 16 of the bumper stay 20 to be caulked to the rear inclined wall 14.SELECTED DRAWING: Figure 1B

    【課題】形状や材料についての制限を受けることなく、コスト低減して簡単にバンパーステイとバンパーリインフォースをかしめ接合できるバンパー部材の接合方法を提供する。【解決手段】バンパー部材の接合方法では、穴部16が設けられた後方傾斜壁14を有するバンパーリインフォース10と、中空状のバンパーステイ20とを準備する。そして、バンパーリインフォース10の穴部16にバンパーステイ20を挿通して後方傾斜壁14を貫通させ、バンパーステイ20の内部にゴム30を挿入し、ゴム30をバンパーステイ20の軸線L方向に圧縮して内側から外側に向けて膨張させ、それによってバンパーステイ20の少なくとも穴部16に挿通された部分を拡大変形させて後方傾斜壁14にかしめ接合する、バンパー部材の接合方法。【選択図】図1B
