Abstract

PROBLEM TO BE SOLVED: To provide a golf club which imparts the feel of stability to a player. SOLUTION: This golf club is set at θ>θ1<=0 when the angle of inclination of an axis AX of a main body 15 of the club shaft 13 with a perpendicular PL to the head 12 is defined as θ and the angle of inclination of the axis AX1 of a pendent part 14A interposed between the main body 13 and a root end 14 to the perpendicular PL as θ1. Such feel of stability as if the head 12 is hung down from the shaft 13 may be imparted to a player by the pendent part 14A.
