To provide metal tubular materials in which a bent surface portion and an attachment surface portion surface-contactable with other members are stably disposed and thereby the number of components required to be fixed to other members can be reduced.SOLUTION: Bent portions 34 are disposed between a cylinder portion 30 and an attachment surface portion 32A. The bent portions 34 are bent inward of the cylindrical portion 30 on the cylindrical portion 30 side of a pair of peripheral edge portions 32A1 of the mounting surface portion 32A, which extend in the extension direction of the mounting surface portion 32A, and bent outward of the cylindrical portion 30 on the cylindrical portion 30 side between the pair of peripheral edge portions 32A1.SELECTED DRAWING: Figure 1

    【課題】金属製の管材において、曲面部と、他部材に面接触可能な取付面部とを安定した状態で設けて、他部材との固定に必要な部品点数を低減することができる管材を得る。【解決手段】円筒部30と取付面部32Aとの間に曲げ部34が介在されている。この曲げ部34は、取付面部32Aにおける取付面部32Aの延出方向に延びる一対の周縁部32A1の円筒部30側では円筒部30の内側に向かって折り曲げられ、一対の周縁部32A1間における円筒部30側では円筒部30の外側に向かって折り曲げられている。【選択図】図1
