Abstract (en)
A putter club is provided which enables accurate putting by maintaining an angle of a ball-hitting surface with respect to the horizontal plane during a swing. When a player holds a grip (111) with both hands and back-swings from an address position, a shaft (110) is inclined toward a positive side of an X-axis. In this process, the head (130) is pivoted by its own weight around a rotational axis (124) which is horizontal, which is parallel to the ball-hitting surface (131), and which passes through a center of mass of the head, and an angle of the ball-hitting surface with respect to the horizontal plane is maintained. In the process from start of the swing through an impact to a follow-through, the shaft is inclined toward a negative side of the X-axis. During this process also, the head is pivoted by its own weight around the rotational axis, and the angle of the ball-hitting surface with respect to the horizontal plane is maintained.
