    • PROBLEM TO BE SOLVED: To provide a rubber thread golf ball that gives a good feeling of hitting, a long carry and a good spin performance.
      SOLUTION: A thread golf ball consists of a rubber thread layer wund with rubber thread around the center and a cover over the outside thereof. The volume of the rubber thread layer occupies 10 to 20% of the total volume of the golf ball. Where the amount of deformation (mm) from the position when a load of 98 N is applied to the center to that when a load of 1274 N is applied, is A and the amount of deformation (mm) from the position when a load of 98 N is applied to the rubber thread over core to when a load of 1274 N is applied is B, (A-B) is 0.5-0.7. The cover is formed of a thermosetting resin as a principal component and the Shore D hardness is 50 to 60.

    • PROBLEM TO BE SOLVED: To provide a golf ball keeping a good ball hitting feeling peculiar to a thread winding golf ball and having a large carry. SOLUTION: This thread winding golf ball includes a solid center, a thread rubber layer formed by winding round the surface of the solid center, and a cover for covering the surface of the thread rubber layer, and the golf ball has dimples formed on the surface of the cover. When load of 9.8 N to 294 N is applied to the solid center, the deformation amount of the solid center is 1.0 to 1.5 m, the difference (A1-A2) between the diameter A1 of the solid center and the thickness A2 of the thread rubber layer is 34.5 to 36.5 mm, the Shore D hardness of the cover is 44 to 58, and the dimple volume rate Rv and the difference (A1-A2) between the diameter of the solid center and the thickness of the thread rubber layer satisfy the following expression: 2.45
