Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a National Stage of International
Application No. PCT/JP2020/025829 filed on Jul. 1, 2020, which
claims priority to and the benefit of Japanese Patent Application
No. 2019-235528, filed on Dec. 26, 2019, the contents of which are
incorporated herein by reference in their entirety.
FIELD
[0002] The present disclosure relates to a golf club with a golf
club head.
BACKGROUND
[0003] Techniques for attaching a weight to a golf club head have
been proposed so far to adjust the weight and weight balance of the
golf club head. For example, JP 11-9742 A discloses a golf club
head in which a plurality of weight attachment portions are
provided on the sole portion of the club head body along a
direction substantially orthogonal to the hitting surface, and
weight adjustment members of appropriate weights and sizes are
selectively attached to the weight attachment portions.
[0004] In addition, techniques for attaching a balance weight to a
golf club have also been proposed to increase the swing speed of
the golf club. For example, JP 3052898 U discloses a golf club
provided with a balance weight at the grip end of the golf
club.
