<p>PURPOSE:To provide a metal wood club where the dimensional accuracy of a lie-loft angle is high and the adjustment is easy and the junction strength between the head and the hosel part is high. CONSTITUTION:The soul part of a head is provided with an irregular positioning part 2, and the extension 3a and the positioning part 2 are junctioned and fixed to each other, and the open part of the head 1 and the hosel part 3 are junctioned and fixed to each other. Hereby, the junction strength between the head part 1 and the hosel part 3 goes higher than before, so it can prevent breakage, cracks, etc., from occurring in the junction between the head 1 and the hosel part 3 during shooting. Moreover, since the extension 3a of the hosel part 3 is junctioned to the positioning part 2, the arranging position of the hosel part 3 and be decided accurately in a short time. Therefore, the dimensional accuracy of a lie-loft angle after junction is high, and the adjustment can be performed in a short time as compared with before.</p> |
