ABSTRACT:
A shaft for a golf club includes a tubular main body made of a fiber-reinforced resin and being 10 mm or less in the outside diameter of the tip of the body. The outside circumferential surface of the main body is tapered from the butt thereof to the tip thereof at a ratio of 0/1,000 to 4/1,000 so as to be nearly uniform in diameter. The thickness of the main body is gradually increased from the tip thereof to the butt thereof. The golf club having the shaft, receives a low resistance of air, and has a rigidity appropriate for a powerful golfer who swings the club quickly.
