    摘要: A golf ball mold including a spherical cavity having a large number of projections for shaping dimples on the inner wall surface with a parting surface provided at a position substantially corresponding to an equator of the cavity, provided with a plurality of core support pins elongating reciprocally movably on a circle centering on each pole of the cavity of the upper mold or the lower mold with a predetermined radius with a predetermined distance with each other in the cavity in the direction perpendicular to the parting surface. In the golf ball mold, the support pins have a dimple shaping projection at the tip portion thereof having a round shape on the cavity wall surface level, protruding from the position to the cavity center direction when the support pins are withdrawn to the cavity wall surface position.

    摘要: 1. A golf ball having a generally spherical outer surface and a center, the outer surface being provided with a plurality of dimples, at least some of the dimples having a surface with an elliptical cross section which is a portion of an ellipse defined by the equation:X.sup.2 /A.sup.2 +(Y-k).sup.2 /B.sup.2 =1where X is a coordinate on an X axis which extends perpendicularly to a radial line from the center of the ball to the center of the ellipse, Y is a coordinate on a Y axis which is aligned with said radial line, A is one-half of the major axis of the ellipse which is aligned with said X axis, B is one-half of the minor axis of the ellipse which is aligned with said Y axis, and K is the distance along the Y axis between the center of the ellipse and the center of the golf ball.
