Description

The present invention relates to a fishing thread guide, a fishing rod provided with the fishing thread guide, and a method for molding the fishing thread guide.

Conventionally, various fishing thread guides that are attached to a fishing rod to guide fishing threads have been known. Such a fishing thread guide is configured to include a frame mounted on the outer peripheral surface of the fishing rod and a guide ring that is fixed to the frame and through which the fishing thread is inserted.

As such a fishing thread guide, Patent Document 1 describes a ring holding portion for holding a guide ring through which the fishing thread is inserted into a frame made of metal, and a fixing portion for mounting on the outer surface of the fishing rod. A fishing rod guide integrally formed with the rod is disclosed.

Further, Patent Document 2 discloses that a fishing thread guide having a frame including a frame and a guide ring fixed to the frame and through which the fishing thread is inserted is injection-molded with a fiber reinforced resin.
