キングとして間挿していた。
As shown in FIG. 5, the conventional clarinet bakey and seasharp key joint is made by molding a gourd-shaped male joint 105 with a handle integrally with the manual lever 1, and plugging the male joint 105 into the female hole of the lever 3. 6
In addition, a cover p made of plastic such as vinyl was inserted between the male joint 105 and the female hole 6 as packing.
しかし、このような従来の継手ではおす継手１
０５が金属性のためめす穴６との間に金属音が発
生するだけでなく、摩耗も激しかつた。この場
合、ある程度、プラスチツクのカバーｐでこれら

ｐをあまり厚いものを用いることができないの
で、上記音と摩耗の防止は完全には行ない得なか
つた。 However, in such conventional joints, the male joint 1
Since 05 was made of metal, not only did a metallic sound occur between it and the female hole 6, but the wear was also severe. In this case, even if the plastic cover p can prevent these metal sounds and abrasion to some extent, the cover p cannot be made very thick, so the above noise and abrasion cannot be completely prevented. Ta.

In order to solve the above problems, this invention uses polyacetal resin or ABS as the male joint 5.
The fitting 5 is made of resin or fluororesin and is directly inserted into the female hole 6 without using the conventional plastic cover p.
このような構成をとることにより、本考案は音
の静かな、耐摩耗性の大きい継手を提供しようと
するものである。 By adopting such a configuration, the present invention aims to provide a joint that is quiet and has high wear resistance.
以下図面に基づいて本考案の実施例について説
明する。
Embodiments of the present invention will be described below based on the drawings.
第４図において、ベーキーＢとシーシヤープキ
ーＣ＃の手動レバー１，１は手動レバー回動軸
２，２を中心として回動し、その先端に継手を介
して、孔塞ぎレバー３，３に連結されている。 In Fig. 4, manual levers 1, 1 of bake key B and seasharp key C# rotate around manual lever rotation shafts 2, 2, and are connected to hole closing levers 3, 3 through joints at their tips. connected.
そこで、ベーキーＢとシーシヤープキーＣ＃と
はその駆動系統が全く同一であるので第１〜３図
において、１つにまとめて両者の駆動系統を説明
する。 Since the drive systems of Bakery B and Seasharp Key C# are completely the same, their drive systems will be explained together in FIGS. 1 to 3.
第１〜３図において、手動レバー１は手動レバ
ー回動軸２を中心として回動し、その先端には、
おす継手５が突設されている。このおす継手５は

るテフロン（登録商標）］で作られ、柄の付いた
瓜型をなし、その柄部５ａが手動レバー１の先端
のおす継手挿入穴７に挿入固定されている。 In Figures 1 to 3, a manual lever 1 rotates around a manual lever rotation shaft 2, and has a
A male joint 5 is provided protrudingly. This male joint 5 is made of polyacetal resin [for example, Delrin (registered trademark), a product of DuPont] or ABS resin.
Alternatively, it is made of fluororesin (for example, Teflon (registered trademark), a product of DuPont), and has a melon-shaped handle, and the handle 5a is inserted and fixed into the male joint insertion hole 7 at the tip of the manual lever 1. ing.
なおポリアセタール樹脂の一種であるデルリン
（登録商標）はポリアルデヒトを無水の状体で特
殊な触媒の存在下で重合して得た線状構造の重合
体である。 Note that Delrin (registered trademark), which is a type of polyacetal resin, is a polymer with a linear structure obtained by polymerizing polyaldehyde in an anhydrous state in the presence of a special catalyst.
そして、おす継手５の瓜型部５ｂが直接孔塞ぎ
レバー３のめす穴６に挿入連結される。 Then, the melon-shaped portion 5b of the male joint 5 is directly inserted and connected to the female hole 6 of the hole closing lever 3.
このようにして、手動レバー１の揺動運動は孔
塞ぎレバー３をその回動軸４を中心として回動せ
しめ、各々の孔を開閉する運動を行なう。 In this manner, the swinging motion of the manual lever 1 causes the hole closing lever 3 to rotate about its pivot shaft 4, thereby performing a movement for opening and closing each hole.
おす継手５としてポリアセタール樹脂、あるい
はABS樹脂、あるいは弗素樹脂を用いたので演
奏時音が静かでかつ、耐摩耗性が大きいため長時
間継手の交換の必要がない。
Since polyacetal resin, ABS resin, or fluororesin is used for the male joint 5, the sound is quiet during performance, and the wear resistance is high, so there is no need to replace the joint for a long time.
特に弗素樹脂の一種であるデルリン（登録商標
名）を用いた場合は手動レバー１の手動のときの
抵抗が軽やかで、伝動効率も高く、音が静かであ
る特徴がある。 In particular, when Delrin (registered trademark), which is a type of fluororesin, is used, the resistance when the manual lever 1 is operated manually is light, the transmission efficiency is high, and the sound is quiet.
