GOLF CLUB HEAD

To provide a golf club head providing tolerance of off center hitting, and approaching a centroid to a place where a golf ball may be hit.SOLUTION: A golf club head 100 comprises a centroid 170 which is arranged at an interval of less than 5 mm from a vertical center plane 166 which is vertical to a face surface and extends passing a center of a hitting face. A golf club head 100 further includes a first component having a first melting point and first density, and a second component having a second melting point greater than the first melting point and second density lower than the first density. The second component is configured so that:(i) the second component is at least partially sealed by the first component; (ii) the second component extends to a hosel part below a hosel bore; and (iii) the second component has mass of less than almost 5 g.SELECTED DRAWING: Figure 1 【課題】オフセンター打撃の寛容性を提供しつつ、重心をゴルフボールが打たれそうな場所に近づける。【解決手段】ゴルフクラブヘッド１００は、フェース面に垂直であり、かつ、打撃フェースの中心を通って延びる垂直中心面１６６から５mm未満を隔てて配置された重心１７０を含む。ゴルフクラブヘッド１００はまた、第１の融点及び第１の密度を有する第１の構成要素と、前記第１の融点より高い第２の融点及び前記第１の密度よりも低い第２の密度を有する第２の構成要素を含む。そして、前記第２の構成要素は、（i）前記第１の構成要素によって少なくとも部分的に封止され、（ii）ホーゼルボアの下のホーゼル部に延在し、（iii）約５ｇ未満の質量を有する。【選択図】図１
