The contour of each dimpleis composed of a first circular arc, a second circular arc, a first connection line, and a second connection line. The curvature radius R2 of the second circular arcis larger than the curvature radius R1 of the first circular arc. The first connection lineis a straight line. The first connection lineconnects one endof the first circular arcto one endof the second circular arc. The second connection lineis a straight line. The second connection lineconnects the other endof the first circular arcto the other endof the second circular arc.
