フクラブのヘツド。[Claims for Utility Model Registration] 1. A face surface curved into a convex curve and having a predetermined loft angle, and a plurality of face lines formed on the face surface from the toe side to the heel side. In the head of a golf club having a face line, the face line is formed in an arcuate shape having a center of curvature below the head when viewed from the front of the head so that the face line appears almost straight when viewed from above the head at address. A golf club head characterized by: 2 The radius of curvature of the face formed into a spherical shape is R
Let the loft angle of the head be Θ, and set the angle between the line connecting the approximate center point of the face surface and the center of curvature of the face surface and the polar coordinate axis that intersects the center of curvature of the face surface to be the same as the loft angle Θ. When the polar coordinate axes are determined, the center of curvature of each face line is located on the polar coordinate axis when viewed from the front of the head,
The golf ball according to claim 1, wherein each face line is formed in a concentric arc shape when viewed from the front of the head so that the radius of curvature r of each face line satisfies the relationship r=R sin θ with respect to the polar coordinate axis. club head. 3. The head of a golf club according to claim 1 or 2, wherein the face line is formed so that the center of curvature of the face line is located almost directly below the sweet spot of the face surface when the head is viewed from the front. 4. The head of a golf club according to claim 1 or 2, wherein the face line is formed such that the center of curvature of the face line is located closer to the toe than directly below the sweet spot of the face surface when the head is viewed from the front. 5. The golf club head according to claim 1 or 2, wherein the face line is formed such that the center of curvature of the face line is located closer to the heel than directly below the sweet spot on the face surface when the head is viewed from the front.
