| 摘要 |
A golf club shaft which includes a tubular inner layer formed of a first, fiber-reinforced plastic and containing a first fiber group wound at a first winding angle within the range of 20 DEG -45 DEG relative to the longitudinal shaft axis and an outer layer formed of a second, fiber-reinforced plastic and containing a second fiber group wound at a second winding angle within the range of 5 DEG -30 DEG relative to the longitudinal shaft axis, the outer layer being integrally bonded onto the outer surface of the inner layer, the first winding angle at any point in the longitudinal direction of the shaft being greater than the second winding angle at that point, the second winding angle being maximum at a point intermediate the length of the shaft and being smaller toward both ends of the shaft.
