Golf shaft series and manufacturing method of golf shaft series

摘要

PROBLEM TO BE SOLVED: To provide a golf shaft series made of fiber reinforced resin in which a hardness adjustment of shaft is easy and a flexure condition of several shafts with different hardness can be arranged easily, and provide a manufacturing method of the same.SOLUTION: A golf shaft series made of fiber reinforced resin includes first and second shafts attached to golf clubs of the same club number. The first and second shafts include a braid layer 12 for adjustment formed by knitting braids 11 constituted by impregnating resin 43 in a fiber bundle 42 comprising multiple fibers 41. The braids 11 of the braid layer 12 for adjustment in the first and second shafts have multiple first slant threads 21 and multiple second slant threads 22 having a symmetric slant angle to an axial direction of the shaft, and a center thread 23 along the axial direction of the shaft. The total number of fibers constituting the central thread 23 of the first shaft is different from the total number of fibers constituting the central thread 23 of the second shaft.SELECTED DRAWING: Figure 2
