しかしながら、特開２００３-６２１３１号公報に開示の発明は、ゴルフクラブヘッド２０１のソール面２０２に添着された円盤２０３を回動させることにより、ロフト角等を変えるものであるため、ゴルフ規則のゴルフクラブに関する付属規則に抵触する恐れがあって、公式競技で使用することは難しい。
また、特願２００６-５３１３０８号の発明は、ゴルフクラブ購入後にゴルフクラブのロフト角等をプレイヤーの体形や好みに応じて容易に、かつ、微妙に変えることができ、公式競技でも使用可能なゴルフクラブではあるが、ソールウエイト３２８を縁部から立上る周壁を有するボックス型としているため、ソールウエイト３２８内に水が滞留する恐れがあるとともに、ソールウエイト３２８の周壁がソール凹み部２２４の底面に線接触しているため、線接触しているソール凹み部２２４の底面に過大な押圧力が掛かる恐れがある。 However, the invention disclosed in Japanese Patent Application Laid-Open No. 2003-62131 changes the loft angle and the like by rotating the disk 203 attached to the sole surface 202 of the golf club head 201. It is difficult to use in official competitions, as it may conflict with club rules.
In addition, the invention of Japanese Patent Application No. 2006-531308 allows golf clubs to be used in official competitions, with the golf club's loft angle etc. being easily and subtly changed according to the player's body shape and preferences after purchase. Although it is a club, since the sole weight 328 has a box shape having a peripheral wall rising from the edge, there is a possibility that water may stay in the sole weight 328, and the peripheral wall of the sole weight 328 is formed on the bottom surface of the sole recess 224. Since it is in line contact, an excessive pressing force may be applied to the bottom surface of the sole recess 224 in line contact.

そこで、本願発明は、ゴルフクラブ購入後であってもゴルフクラブのロフト角等をプレイヤーの体形や好みに応じて容易に、かつ、プレイヤー自身やゴルフショップなどがプレー中以外で微妙に変えることができるとともに、公式競技でも使用可能で降水中に使用しても水が滞留する恐れがなく、ソール凹み部の底面に過大な押圧力が掛かる恐れがないゴルフクラブを提供することを目的とする。 Therefore, the present invention can easily change the loft angle of the golf club according to the player's body shape and preference even after the purchase of the golf club, and can be subtly changed except when the player himself or the golf shop is playing. Another object of the present invention is to provide a golf club that can be used in official competitions, does not cause water to stay when used in precipitation, and does not cause excessive pressing force on the bottom surface of the sole recess.
