Golf club head
First Claim
1. A golf club head comprising:
- a head body;
a socket attached to the head body; and
a weight body capable of being attached to or detached from the socket,wherein the weight body can be attached or detached by relative rotation of an angle θ
to the socket;
the weight body has an engaging part;
the socket has a first hole part and a second hole part;
hardness Hs of the second hole part is D40 or greater and D58 or less;
the engaging part can take an engaging position EP and a non-engaging position NP in the second hole part by the relative rotation of the angle θ
;
the second hole part has a resistance surface elastically deformed in the middle of the relative rotation; and
when a longest sectional size of the engaging part is defined as d1, and a distance between the resistance surfaces opposed to each other is defined as F1, F1/d1 is 0.935 or greater and 0.965 or less; and
when a distance between opposed surfaces of the engaging part is defined as c1, and an opening width of the first hole part is defined as K1, a difference (K1−
c1) is 0.3 mm or greater and 0.6 mm or less.

Abstract
A head 4 includes a head body h1, a socket 10, and a weight body 12. The weight body 12 has an engaging part 32. The socket 10 has a first hole part 18 and a second hole part 20. The engaging part 32 can take an engaging position EP and a non-engaging position NP in the second hole part 20 by relative rotation of an angle θ. Hardness Hs of the second hole part 20 is D40 or greater and D58 or less. The second hole part 20 has a resistance surface 84 elastically deformed in the middle of the relative rotation. A longest sectional size of the engaging part 32 is defined as d1, and a distance between the resistance surfaces 84 opposed to each other is defined as F1, a ratio (F1/d1) is 0.935 or greater and 0.965 or less.
