Abstract
The present invention refers to a golf ball having projections in a form of dome, in a form of cut sphere, in a form of polyhedron, in a form of spherical polyhedron, in a form of which the base is in polygon and the sides are round and plane like the side of cut cone, in a form of which the base is in circle and the sides are round and plane like the side of cut cone or with a small dome put on each of cut top. The surface of the said inner cover can be made of projections of one kind on the whole or projections of a different kind. Meanwhile, it is possible to make the projections of one kind or more than two kinds that are different in a size or height. The said projections also may be apart from each other at regular intervals or may be in contact with each other, and in some cases, some projections may be in contact and some projections apart from each other. When hitting a golf ball having the projections on the surface of inner cover, the energy from outer cover can be transmitted to the inside of core by the said projections faster than other common golf balls having inner cover in a fixed thickness, so as to extend the carry and also having a good spin property.
