To provide an injection molded pipe member having a high quality, the pipe
member is integrally provided with a holder portion (20), a pipe portion
(30) and ribs (40) arranged in an outer periphery of the pipe portion
(30) at a uniform interval in peripheral direction, protruding in radial
direction and reaching the holder portion (20) from a middle of the pipe
portion (30), and has a resin injecting position (20f) in a surface of a
portion except the pipe portion (30) and the ribs (40), so that molten
resin flows quickly through the forming space uniformly in peripheral
direction without being deflected when injection molding, thereby bend of
the pipe portion (30), thickness shrink, and forming die breakage is
prevented.
