To provide a joining method of a member which has a high joint strength for a force of such a direction that a tube body is drawn out of a hole part, and a joined body.SOLUTION: A bumper system 1 includes a rear wall 12 of a bumper beam 10 provided with hole parts 16, 17 and tubular parts 21, 22 elongated in a longitudinal direction. Therein, the tubular parts 21, 22 are inserted to the hole parts 16, 17 and include a bumper stay 20 pipe-expansion joined to the hole parts 16, 17. The bumper stay 20 has a drawing hindrance part 24 which protrudes from an outer surface of the tubular parts 21, 22 on a cross-section vertical to the longitudinal direction. The drawing hindrance part 24 is abutted to the rear wall 12 of the bumper beam 10 in such a direction A1 that the bumper stay 20 is drawn from the hole parts 16, 17.SELECTED DRAWING: Figure 7

    【課題】管体が孔部から引き抜かれる向きの力に対して、高い接合強度を有する部材の接合方法および接合体を提供する。【解決手段】バンパーシステム1は、孔部16,17が設けられたバンパービーム10の後壁12と、長手方向に延びる管状部21,22を有し、管状部21,22が孔部16,17に挿通されるとともに孔部16,17に対して拡管接合されたバンパーステイ20とを備える。バンパーステイ20は、長手方向に垂直な断面において管状部21,22の外面から突出する引抜障害部24を有している。引抜障害部24は、バンパーステイ20が孔部16,17から引き抜かれる向きA1においてバンパービーム10の後壁12に当接している。【選択図】図7
