しかしながら、前述のハンダなどによって固着させて構成した内視鏡用測定具 では、ハンダなどを可撓性密巻きコイルの外側から流し込んでいたため、可撓性 密巻きコイルと先端部材の嵌合部との嵌合部分に、ハンダなどが十分に流れ込ん でいるかどうかの確認ができなかった。このハンダなどの流れ込む量のバラツキ により可撓性密巻きコイルと先端部材との接続は、嵌合部分にハンダなどが十分 に流れ込んでいるものと、嵌合部分にハンダなどが小量しか流れていないものが できて、必要な固定強度を安定して得ることができない恐れがあった。 However, the measuring tool for an endoscope configured by being fixed with the aforementioned solder etc. In this case, solder etc. were poured from the outside of the flexible tightly wound coil, so the flexible Make sure that enough solder etc. flows into the fitting part between the tightly wound coil and the fitting part of the tip member. I couldn't confirm whether it was there or not. Variations in the amount of solder flowing in Therefore, the connection between the flexible tightly wound coil and the tip member should be made with sufficient solder etc. on the mating part. There are cases where solder has flowed into the mating area, and cases where only a small amount of solder has flowed into the mating area.
