Abstract
Official abstract text for this publication.
One object is to provide a fishing line guide including a high-hardness guide ring and a fishing rod provided with said fishing line guide. A fishing line guide according to one embodiment of the present invention includes a guide body with a through hole formed therein and a guide ring fitted into the through hole of the guide body. In one aspect, the guide ring includes a base material layer and a surface layer formed on a surface of the base material layer. In one aspect of the present invention, the base material layer is formed of an alloy having an Fe content of 3 wt % or less or 2 wt % or less. In one aspect of the present invention, the surface layer is formed of chromium carbide, titanium carbide, or vanadium carbide.
First claim
Opening claim text (preview).
What is claimed is: 1. A fishing line guide, comprising: a guide body with a through hole formed therein; and a guide ring fitted into the through hole of the guide body, wherein the guide ring includes: a base material layer; and a surface layer formed on a surface of the base material layer, the base material layer is formed of an alloy having an Fe content of 3 wt % or less, the surface layer is formed of chromium carbide, titanium carbide, or vanadium carbide, the guide ring is curved into a convex form toward an inner peripheral side as viewed in a cross section cut along a plane including an axial direction of the guide ring, and the guide ring is curved so that a gap is formed between an outer peripheral surface of the guide ring and an inner peripheral surface of the guide body, and the fishing line guide further comprises an adhesive arranged in said gap. 2. The fishing line guide according to claim 1 , wherein the base material layer has an Fe content of 2 wt % or less. 3. The fishing line guide according to claim 1 , wherein the base material layer is formed of an alloy containing Ni, Co, Cr, Mo, and Fe. 4. The fishing line guide according to claim 1 , wherein the guide ring is curved so that a front surface of a rear end portion thereof comes in contact with a rear surface of the guide body. 5. The fishing line guide according to claim 1 , wherein the guide ring is curved so as to come in contact at a front end surface thereof with an inner peripheral surface of the through hole of the guide body. 6. The fishing line guide according to claim 1 , wherein the surface layer is formed of chromium carbide and has a thickness of 10 μm to 30 μm. 7. The fishing line guide according to claim 1 , wherein the surface layer is formed on the surface of the base material layer on an outer peripheral side. 8. The fishing line guide according to claim 1 , wherein a front end portion of the guide ring is positioned posterior to a front surface of the guide body in an axial direction of the guide ring. 9. A fishing rod comprising at least one fishing line guide as claimed in claim 1 .
