<p>A golf club shaft includes a tubular inner layer formed of a first, fiber-reinforced plastics and containing a first fiber group wound at a first winding angle within the range of 20-45 DEG against the 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 5-30 DEG against the shaft axis, said out layer being integrally bonded onto the outer surface of said 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 in an intermediate portion on the longitudinal direction of the shaft and being smaller toward both ends of the shaft. <IMAGE></p> |
