本考案は、ガツトの振動吸収材を備えたラケツ
トに関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a racket equipped with a gut vibration absorbing material.
（従来技術）
例えばテニスのプレイ中のように、ガツトが張
られたラケツトによりボールを打つと、かなりの
衝撃を受けるためラケツトに強い振動が生じる場
合があり、この振動により、ラケツトの使用者が
しびれを感じたり、腕を痛めたりする恐れがあ
る。(Prior art) For example, when you hit a ball with a racket that has been tightened, as in the case of playing tennis, the racket receives a considerable impact and may generate strong vibrations. You may feel numbness or hurt your arm.
このような問題を解決するため、従来では、ガ
ツトの振動を吸収するために、柔軟性を有する弾
性材もしくは粘弾性材からなる振動吸収帯を、す
でにガツトが張られた状態にあるラケツトに対し
て、複数のガツトに巻きつけるように取付ける構
成のものがある（特開昭60−168473号公報）。 To solve this problem, in the past, in order to absorb the vibrations of the strings, a vibration-absorbing band made of a flexible elastic material or a viscoelastic material was attached to the racket with the strings already tensioned. There is a structure in which it is attached so as to be wrapped around multiple guts (Japanese Unexamined Patent Publication No. 168473/1983).
しかし、このような構成は一般に、ガツトが張

ないかとの不安も生じる。 First, when replacing the guts, the vibration-absorbing band must be removed, and there is a risk of losing the vibration-absorbing band. Furthermore, if the vibration absorbing band is removed many times, since the vibration absorbing band is very thin, it is likely to crack or peel, which may lead to breakage. Moreover, since the above-mentioned vibration absorption bands are small, it is often the case that multiple identical ones are attached to the racket in order to increase their effectiveness, which detracts from the aesthetic appearance of the racket.
There is also a fear that the ball will hit this vibration absorption band when hitting the ball.
また、上記振動吸収帯を複数本のガツトに巻き
つけることにより、各ガツトの巻きつけられた部
分の間隔が変化して、ガツトが平行でなくなるた
め、打球時にイレギユラが生じることもある。 Furthermore, by wrapping the vibration absorbing band around a plurality of strings, the distance between the wound portions of each string changes, and the strings are no longer parallel, which may cause irregularities when hitting the ball.
