Putter face and golf putter having putter face inserted therein
Abstract:
In order to solve a problem of a shift of a rebounding direction due to a contact of a golf ball and a ball contact surface of a putter face, while attaining an initial velocity, a striking touch, and a sense of distance, each of which are compared favorably to a metal face, a putter face is arranged including hexagonal posts (4) each made of material having a higher rigidity than a ball (7), the hexagonal posts (4) having a contact surface (41) which has contact with the ball (7), and impact-absorbing rings (5) made of material having a lower rigidity than that of the hexagonal posts (4), so as to elastically support the hexagonal posts (4) in a normal direction of the contact surfaces (41), wherein the plurality of hexagonal posts (4) are juxtaposed in an in-plane direction of the contact surfaces (41) and the contact surfaces (41) constitute a single surface when the ball (7) is not in contact with the contact surfaces (41).
