In an intra-line fishing rod, a rod tube comprises a synthetic resin as a matrix, and is reinforced by reinforced fibers. A guide is formed integrally with and projects from an inner surface of the rod tube. A cushioning portion is formed between the guide and a body layer of the rod tube which is composed predominantly of axially-extending fibers, and cushioning portions are formed respectively at front and rear sides of the guide connected to the inner surface of the rod tube. The cushioning portions are smaller in bending modulus than a bulge portion region of the guide for contact with a fishline, and the inner surface is formed with a mirror-like smoothness.

Intra-line fishing rod

The invention concerns a fishing rod in which a fishline is passed through the inside thereof. In the fishing rod, one of front and rear rod pipes to be connected together is provided with an enlarged diameter portion for receiving an outer periphery of the other rod pipe. Such enlarged diameter portion reduces a difference between the inside diameters of the front and rear rod pipes, to thereby eliminate the possibility that the fishline can be abutted against the end portion of the rod pipes. Thus, the frictional resistance of the fishline can be decreased, so that the fishline can be smoothly drawn into and out of the rod pipes.

Fishing rod with inserted fishline

The invention relates to a fishing rod with pre-inserted fishing line guide members. A prepreg formed of a high-strength fiber impregnated or mixed with resin is wound to form the rod pipe. A plurality of wide fishing line guide members each having a flat-shaped section are fixed integrally to the inner peripheral surface of the rod pipe, the inner peripheral side portions of the wide fishing line guide members are respectively projected inwardly from the rod pipe inner peripheral surface, and the outer portions of the rod pipe existing in the wide fishing line guide fixed portions are respectively bulged outwardly and widely. The fishing line guide members are strongly fixed to the inner peripheral surface of the rod pipe without lowering the strength of the rod pipe.

The invention relates to a fishing rod with preinserted fishing line guide members. A prepreg formed of a high-strength fiber impregnated or mixed with resin is wound to form the rod pipe. A plurality of wide fishing line guide members each having a flat-shaped section are fixed integrally to the inner peripheral surface of the rod pipe, the inner peripheral side portions of the wide fishing line guide members are respectively projected inwardly from the rod pipe inner peripheral surface, and the outer portions of the rod pipe existing in the wide fishing line guide fixed portions are respectively bulged outwardly and widely. The fishing line guide members are strongly fixed to the inner peripheral surface of the rod pipe without lowering the strength of the rod pipe.

The present invention relates to a fishing rod having a rod tube formed from synthetic resin-impregnated high strength fiber and to a production method thereof. The rod tube of the present fishing rod is filled with resin containing microglobules in a dispersed state. This makes a lighter and stronger fishing rod which withstands extreme deflection. The production method according to the present invention can adjust the ratio of the filled resin and the dispersed microglobules at the tip and butt portions of the rod. Accordingly, the weight, strength, and condition for each portion of the rod can be controlled as required.
