PROBLEM TO BE SOLVED: To provide a door channel with restrained occurrence of wrinkles during a bending process.SOLUTION: A frame 3 is provided integrally with a vertical frame part 10a extending in a vertical direction of a vehicle, a horizontal frame part 10b extending in a longitudinal direction of the vehicle, and a corner part C, which is connecting between the horizontal frame part 10b and the vertical frame part 10a and is a curved and bent part formed by a bending process. A curve part 33C and a straight line part 33S formed by the corner part C appear on an outer edge of an outer peripheral wall part 33. A notch K0 opening at an inner corner of the corner part C is provided in an inside wall 32 being a sidewall part. Both ends KE of the notch K0 extend up to a position beyond a boundary B between the curve part 33C and the straight line part 33S formed by the corner part C.SELECTED DRAWING: Figure 5 【課題】折り曲げ加工時のしわの発生が抑制されたドアチャンネルを提供すること。【解決手段】フレーム３は、車両の上下方向に延びる縦フレーム部分１０ａと、車両の前後方向に延びる横フレーム部分１０ｂと、横フレーム部分１０ｂと縦フレーム部分１０ａとを接続し折り曲げ加工により形成された湾曲した折り曲げ部分であるコーナ部分Ｃと、を一体に有し、外周壁部３３の外縁には、コーナ部分Ｃによる曲線部３３Ｃと直線部３３Ｓとが現れており、側壁部である内側壁３２にはコーナ部分Ｃの内方の角部に開口する切欠きＫ０が設けられており、切欠きＫ０の両端ＫＥは、コーナ部分Ｃによる曲線部３３Ｃと直線部３３Ｓとの境界Ｂを超えた位置まで延びている。【選択図】図５
