    摘要: A golf ball includes oval dimples arranged on the surface thereof. Each of the oval dimples has a long diameter DL and a short diameter DS in a planar shape thereof and further having a depth DPL on a first cross section of the oval dimple along the long diameter DL and a depth DPS on a second cross section of the oval dimple along the short diameter DS, the depth DPL being a distance taken on the first cross section along the long diameter DL from a first line connecting both ends of the first cross section of the oval dimple to a deepest point of a dimple bottom surface, the depth DPS being a distance taken on the second cross section along the short diameter DS from a second line connecting both ends of the second cross section of the oval dimple to a deepest point of a dimple bottom surface, a relationship between the depth DPL and the depth DPS being defined as a following formula (1): DPS>DPL  (1). Each of the oval dimples further having a cross-sectional area DLA on the first cross section of the oval dimple along the long diameter DL and a cross-sectional area DSA on the second cross section of the oval dimple along the short diameter DS, the cross-sectional area DLA being surrounded by the first line connecting both ends of the first cross section of the oval dimple and the bottom surface thereof, the cross-sectional area DSA being surrounded by the second line connecting both ends of the second cross section of the oval dimple and the bottom surface thereof, a relationship between the cross-sectional area DLA and the cross-sectional area DSA being defined as a following formula (2): DLA≧DSA  (2).

    摘要: A golf ball 2 has a large number of dimples 8 on a surface thereof. A trajectory of the golf ball 2 is divided into first to fourth segments. An average CD1 of drag coefficients CD and an average CL1 of lift coefficients CL in the first segment are equal to or less than 0.225 and 0.180, respectively. An average CD2 of drag coefficients CD and an average CL2 of lift coefficients CL in the second segment are equal to or less than 0.250 and 0.220, respectively. An average CD3 of drag coefficients CD and an average CL3 of lift coefficients CL in the third segment are equal to or greater than 0.260 and 0.220, respectively. An average CD4 of drag coefficients CD and an average CL4 of lift coefficients CL in the fourth segment are equal to or greater than 0.250 and 0.200, respectively.

    摘要: [Problem to be solved] To provide a golf ball with improved flight distance due to improvement in aerodynamic properties by means of contriving dimple designs. The golf ball is in the shape of a sphere and is composed of dimples and lands excluding dimples, wherein said dimples are formed by elliptical dimples together with circular dimples, wherein one said elliptical dimple overlaps said circular dimples at both end parts in its major axis direction, said circular dimples and said elliptical dimples are connected with each other, and one said land is formed between three said elliptical dimples.

    摘要: Golf balls include dimples for generating a turbulent boundary layer. At least some of the dimples include a fan-shape. The fan-shaped dimple has a plurality of blades. Each blade has a trailing edge flush with a land area of a spherical surface of the golf ball, a leading edge, and a side wall connected to the leading edge. The dimple also has a sloped floor extending from the trailing edge to the leading edge, a blade tip connecting the leading edge to the trailing edge at a distal end of the blade, and a blade root connecting the leading edge to the trailing edge at a proximal end of the blade.

    摘要: A golf ball includes oval dimples arranged on the surface thereof. Each of the oval dimples has a long diameter DL and a short diameter DS in a planar shape thereof, a relationship between the long diameter and the short diameter being defined as a following formula (1). DL≦DS×1.2  (1) Each of the oval dimples further has a cross-sectional area DLA on the first cross section of the oval dimple along the long diameter DL and a cross-sectional area DSA on the second cross section of the oval dimple along the short diameter DS, the cross-sectional area DLA being surrounded by a line connecting both ends of the first cross section of the oval dimple and the bottom surface thereof, the cross-sectional area DSA being surrounded by a line connecting both ends of the second cross section of the oval dimple and the bottom surface thereof, a relationship between the cross-sectional area DLA and the cross-sectional area DSA being defined as a following formula (2). DLA≧DSA  (2) The surface coverage SR of all dimples on the surface of the golf ball is at least 70%.
