Abstract:
A pipe-shaped member of the present invention is a pipe-shaped member (1) which includes a flat plate portion (1h1, 1h2) placed in at least one end portion (1a1) of two end portions of the pipe, formed in a flat plate shape, and including groove-shaped recessed portions (ta1, tb1, tb2) formed in one and another extended surfaces in the flat plate shape. The recessed portions (ta1, tb1, tb2) are formed such that the flat plate portion (1h1, 1h2) has at least a substantially W-shape, in a direction crossing a longitudinal direction of the flat plate portion (1h1, 1h2), and with a depth not reaching a boundary (1ha) between one plate (1h1) and the other plate (1h2) of the flat plate portion (1h1, 1h2).
