Abstract

Provided is a fishing line guide capable of not only reducing the weight while securing the rigidity and strength of the entire guide but also reducing the occurrence of line twisting and line tangling during actual fishing, and a fishing rod comprising the fishing line guide. A fishing line guide according to an embodiment of the present disclosure comprises: a fishing line guiding portion formed with a through-hole for guiding a fishing line; a fishing rod fixing portion to be fixed to a fishing rod; and a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, and the fishing line guide is integrally formed of a ceramic material.

Claims (19)

1 . A fishing line guide comprising:

a fishing line guiding portion formed with a through-hole for guiding a fishing line;

a fishing rod fixing portion to be fixed to a fishing rod; and

a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, wherein

the fishing line guide is integrally formed of a ceramic material,

a first outer contour on a first side of the fishing line guide is formed in a concave shape as viewed from a direction perpendicular to a central axis of the through-hole, the concave shape extending along the first outer contour continuously from the connection portion to a first position on a first opening edge of the through-hole, the first opening edge being located at a narrowest portion of the through-hole, and the first position being closest to the fishing rod fixing portion among positions on the first opening edge, and

the first outer contour on the first side of the fishing line guide has no straight portion, and a second outer contour on the first side of the fishing line guide is linear without curves.

2 . The fishing line guide according to claim 1 , wherein a thickness of the fishing line guiding portion increases toward the connection portion as viewed along the direction of the central axis of the through-hole.

3 . The fishing line guide according to claim 1 , wherein a thickness of the connection portion increases toward the fishing rod fixing portion as viewed along the direction of the central axis of the through-hole.

4 . The fishing line guide according to claim 1 , wherein the first outer contour comprises a plurality of arc portions, and the arc portions are connected by one or more inflection points.

5 . The fishing line guide according to claim 1 , wherein the fishing line guiding portion is inclined by 10 to 45° with respect to the fishing rod fixing portion.

6 . The fishing line guide according to claim 1 , wherein a second outer contour on a second side of the fishing line guiding portion is curved in a convex shape as viewed from the direction perpendicular to an axis of the through-hole.

7 . The fishing line guide according to claim 1 , wherein a difference between an outer diameter and an inner diameter of the fishing line guiding portion is in a range of 1.2 mm to 2.0 mm.

8 . The fishing line guide according to claim 1 , wherein a ratio of an inner diameter of the fishing line guiding portion to an outer diameter of the fishing line guiding portion is 0.55 or more.

9 . A fishing rod comprising:

a rod tube; and

a fishing line guide comprising a fishing line guiding portion formed with a through-hole for guiding a fishing line, a fishing rod fixing portion to be fixed to the rod tube, and a connection portion connecting the fishing line guiding portion and the fishing rod fixing portion, wherein

the fishing line guide is integrally formed of a ceramic material, and

a first outer contour on a first side of the fishing line guide is formed in a concave shape as viewed from a direction perpendicular to a central axis of the through-hole, the concave shape extending along the first outer contour continuously from the connection portion to a first position on a first opening edge of the through-hole, the first opening edge being located at a narrowest portion of the through-hole, and the first position being closest to the fishing rod fixing portion among positions on the first opening edge, wherein the first outer contour on the first side of the fishing line guide has no straight portion, and a second outer contour on the first side of the fishing line guide is linear without curves.
