Description
【発明の詳細な説明】 （発明の技術分野） 本発明は、釣り糸ガイドに関する。[Detailed description of the invention] (Technical field of invention) FIELD OF THE INVENTION The present invention relates to fishing line guides.
（発明の技術的背景及びその問題点） 種々の釣りに用いられるリールやサオには。(Technical background of the invention and its problems) For reels and poles used for various types of fishing.
釣りのあらゆる状態に対応できるような機能が要求され
る。なかでも、釣り糸をスムーズにさばくことができ、
かつ糸切れ等の支障を生じないことが１重要である。こ
れらの要求を満たすために、近時釣り糸がイドにセラミ
ックスを用いることが試みられている。しかしながら、
いかなるセラミックスを用いればよいかあるいはどのよ
うな状態のセラミックスを用いればよいかについてはま
だ充分解明されていなかった。A function that can handle all fishing conditions is required. Above all, it can handle fishing lines smoothly,
It is also important that no problems such as thread breakage occur. In order to meet these demands, attempts have recently been made to use ceramics for fishing lines. however,
It has not yet been fully elucidated what kind of ceramics should be used or what state of ceramics should be used.
（発明の目的）
本発明は、釣り用リールやサオに適用して糸切れ２海水
などに対する腐食、摩耗、ワレ等の支障がなく、かつ滑
らかな作動をもたらす釣り糸ガイドを提供する。(Objective of the Invention) The present invention provides a fishing line guide that can be applied to fishing reels and fishing rods and provides smooth operation without problems such as corrosion, abrasion, cracking, etc. due to line breakage, seawater, etc.
（発明の概要）
本発明釣り糸カイトは、緻密な窒化珪素焼結体で構成し
たことを特徴とする。窒化珪素焼結体は、耐熱強度を有
するものとして知られているが２発明者によれば釣り糸
ガイドとしても極めて優れた特性を備えている。(Summary of the Invention) The fishing line kite of the present invention is characterized by being made of a dense silicon nitride sintered body. Silicon nitride sintered bodies are known to have heat-resistant strength, and according to the two inventors, they also have extremely excellent properties as fishing line guides.
特に、緻密に焼結され、かつ糸道にあたる表面を特定の
状態に整えたものは糸耐久性（糸切れ回数等）が著しく
向上する。In particular, yarn durability (number of yarn breakage, etc.) is significantly improved if the yarn is densely sintered and the surface corresponding to the yarn path is prepared in a specific condition.
窒化珪素焼結体は、緻密である方が好ましく密度は３．
０以上であることがよい。The silicon nitride sintered body is preferably dense, with a density of 3.
It is preferable that it is 0 or more.
また、糸道の表面状態は糸耐久性に大きな影響を及ぼし
２表面粗さは０．５μｍ以下がよい。In addition, the surface condition of the yarn path has a great effect on yarn durability, and the surface roughness is preferably 0.5 μm or less.
更に望ましくは０２μｍ以下がよい。また２重要なこと
は表面の気孔の有無である。糸道の表面に大きな気孔が
存在すると糸耐久性を劣化させる。糸道の表面には２０
μｍを越える気孔が存在しないことが望ましい。１０μ
ｍまでの気孔の存在にとどめると更に特性は向上する。More preferably, the thickness is 0.2 μm or less. Another important thing is the presence or absence of pores on the surface. The presence of large pores on the surface of the thread guide deteriorates thread durability. 20 on the surface of the thread path
It is desirable that there be no pores larger than μm. 10μ
If the presence of pores is limited to m, the characteristics are further improved.
このように気孔を極めて小さく緻密に焼結されたＳ ’
ｉ 、 Ｎ、は、その表面状態を０．５μｍ以下に平滑
にすることによって摩耗係数を小さくシ。In this way, the sintered S' has extremely small pores and is densely sintered.
i, N, reduce the wear coefficient by smoothing the surface to 0.5 μm or less.
Ｓｉ３Ｎ、固有の高耐摩性と相まって糸の高速摺動に対
しても長期間にわたって、糸を傷つけることなく使用で
きる。特に糸が海水や砂を付着ワレ、カケなども生じに
くい。Coupled with Si3N's inherent high wear resistance, it can be used for long periods of time without damaging the thread even when the thread is sliding at high speed. In particular, the thread is less prone to cracking or chipping due to adhesion of seawater or sand.
