Abstract:
Provided is a pipe member capable of achieving excellent flexibility and high rigidity. For the pipe member (10), outer ribs (17) for connecting adjacent outer surface protrusions (12) to each other are configured from an upper end (19) connected to one of two adjacent outer surface protrusions (12) and a lower end (20) connected to the other of the two adjacent outer surface protrusions (12). The upper end (19) is formed so as to be shifted from the lower end (20) in the circumferential direction of the pipe body (11). As a result, the outer surface ribs (17) are inclined with respect to the axial direction.
