Golf ball

Abstract

Golf ball has dimples 8. The dimple 8 has a first curved face S1, a second curved face S2, a third curved face S3, a first edge E1, a second edge E2 and a third edge E3. The second edge E2 and the third edge E3 are disposed concentrically with the first edge E1. The first curved face S1 is ring-shaped. The first curved face S1 is inclined downward from the first edge E1 toward the center of the dimple 8. The second curved face S2 is ring-shaped. The second curved face S2 is inclined upward from the second edge E2 toward the center of the dimple 8. The third curved face S3 is bowl-shaped. The third curved face S3 is inclined downward from the third edge E3 toward the center of the dimple 8. The air that flows toward the center of the dimple 8 collides with the third edge E3. Due to this collision, the air flow is disrupted.
