Abstract:
This invention provides a golf club with a club-head configured so as to decrease air resistance of the head by avoiding the air flows from retouching on the head surface. The club-head is provided with a ridge structure which contains a first ridge and a second ridge arranged at intervals in a downward direction of the air flows on at least the sole part of the head, wherein each of the ridges has the height of 0.2 mm to 3 mm and the breadth of 1 mm to 5 mm, the ridge structure being configured by plural ridges so as to displace the inclined angle of the ridges in a clockwise direction, resulting in generation of air vortex or whirls between the head surface and the surrounding air flows.

Claim (Index 1):
A golf-club comprising:\n a club-head including a face at which the club-head is arranged to collide in a first direction with a golf ball, a crown including an upper surface, a bottom surface, and a side surface connecting the upper surface and the bottom surface, and a ridge structure being on a surface of the crown, the ridge structure including a plurality of first ridges and a plurality of second ridges arranged at an interval where a height of the ridge and a length of the interval are decided depending on an average swing head speed to make a vortex flow between the first ridges, the plurality of the first ridges arranged close to the face and extending in a second direction perpendicular to the first direction from a toe side to a heel side on the crown, the plurality of the second ridges arranged behind the plurality of the first ridges and comprised of a pair of L shaped ridges bent from the second direction to the first direction, the interval being larger than a width of each of the plurality of the first ridges.
