In a conventional line guide ring in which a guide ring is fitted into a fixed ring through a chock ring, a recessed groove into which the fixed ring is to be fitted must be provided on the outer periphery of the shock ring. Otherwise a groove is formed on the outer periphery of the guide ring so as not to permit easy disengagement of the respective members.
As the aforesaid groove is needed, such a line guide ring requires not only the formation of such a groove, but also some fitting means in its assembly since it is not mounted merely by press fitting. On the other hand, this guide ring is disadvantageous in that, when there is only a slight difference in dimensions of the respective ring members, it becomes loose upon mounting to a fishing rod, thus becoming rickety or resulting in revolution of the guide ring.
