Abstract: A fishline guider pipe assembly having a detachably screwed guider for an internal fishline type fishing rod. The assembly includes a fishline guider pipe having an inner threaded hole at its middle section and fitted to front and rear pipe pieces of the fishing rod at its hollowed front and rear pipe sections. The inner threaded hole slopes down to the front pipe section and opens to the outside of the guider pipe and to the inside of the front pipe section. The inside end of the inner threaded hole is reduced in its diameter to form an annular stop. The outer threaded cylindrical guider is screwed in the threaded hole for guiding a fishline to the inside of the front pipe section. The inside guide ring is interposed between the annular stop of the guider pipe and an inside end of the cylindrical guider while the outside guide ring is received in the outside end of the cylindrical guider. With this screwthreaded structure, the guider can be separated from the guider pipe when the guider needs repairing.
