Abstract: A head 2 includes a head body h1 and a neck part n1. The head body h1 and the neck part n1 are joined. The head body h1 has a body side joint surface s1 and a first recessed part opened in the body side joint surface s1. A space v1 is formed by the first recessed part r1. The neck part n1 has a neck side joint surface brought into surface contact with the body side joint surface s1 and a shaft hole 14. An abutted boundary surface Pt passes through a vicinity ad1 of a head height lowest point.

Abstract: The golf club head of the present invention includes a face portion, a crown portion, and a sole portion. The golf club head also has an interior space surrounded by the face portion, the crown portion, and the sole portion. A first channel and a second channel that extend in a toe-heel direction and are recessed toward the interior space side are formed in the sole portion. The first channel is disposed on a face side relative to the second channel, and has a first main inner wall disposed on the face side, and a first sub inner wall disposed on a back side. The first main inner wall is formed with a longer length in a face-back direction than the first sub inner wall, and is inclined so as to extend upward while extending toward the back side.

Abstract: In a golf club according to one aspect of the present invention, a first coupling portion of a first adapter, to which the shaft is fixed, and a hosel first coupling portion of the golf club head are coupled so as to be incapable of axial rotation, and thus the shaft is attached to the golf club head so as to not be capable of axial rotation. Accordingly, the second adapter coupled to the first adapter at least does not need to be configured so as to be incapable of axial rotation, thus making it possible to increase the degree of freedom in adapter design.
Abstract translation: 在根据本发明的一个方面的高尔夫球杆中，固定有轴的第一适配器的第一联接部分和高尔夫球棒头的插鞘第一联接部分被联接以便不能轴向旋转 ，因此该轴被附接到高尔夫球杆头以便不能轴向旋转。 因此，耦合到第一适配器的第二适配器至少不需要被配置为不能轴向旋转，因此使得可以增加适配器设计的自由度。
