Abstract

A head 2 includes a face member fc1 formed by casting and a body member bd1 having an opening 20 on a hitting surface 4 side. The opening of the body member bd1 is covered by the face member fc1. The face member fc1 includes a flat plate portion PT forming the hitting surface 4 and a flange FL extending backward from a peripheral edge of the flat plate portion PT. The flange FL includes a first flange FL1 located in a top-side region, and a second flange FL2 located in a sole-side region. The flange FL is not provided in a toe-side region and a heel-side region. The flange FL is joined to the body member bd1.

First claim

What is claimed is:

1. A golf club head comprising:
a face member formed by casting; and
a body member having an opening on a hitting surface side,

wherein:
the opening of the body member is covered by the face member;
the face member includes a flat plate portion forming the hitting surface, and a flange extending backward from a peripheral edge of the flat plate portion;
the flange includes a first flange located in a top-side region, and a second flange located in a sole-side region;
the flange is not provided in a toe-side region and a heel-side region,
the flange is joined to the body member; and
a height H 2 of the second flange is greater than a height H 1 of the first flange.

2. The golf club head according to claim 1 , wherein a thickness T 2 of the second flange is greater than a thickness T 1 of the first flange.

3. The golf club head according to claim 2 , wherein the thickness T 1 is equal to or greater than 0.5 mm and equal to or less than 2.0 mm.

4. The golf club head according to claim 2 , wherein the thickness T 2 is equal to or greater than 0.5 mm and equal to or less than 2.0 mm.

5. The golf club head according to claim 1 , wherein the height H 1 is equal to or greater than 1.0 mm and equal to or less than 5.0 mm.

6. The golf club head according to claim 1 , wherein the height H 2 is equal to or greater than 2.0 mm and equal to or less than 7.0 mm.

7. The golf club head according to claim 1 , wherein a volume of the second flange is greater than a volume of the first flange.

8. A golf club head comprising:
a face member formed by casting; and
a body member having an opening on a hitting surface side,

wherein:
the opening of the body member is covered by the face member;
the face member includes a flat plate portion forming the hitting surface, and a flange extending backward from a peripheral edge of the flat plate portion;
the flange includes a first flange located in a top-side region, and a second flange located in a sole-side region;
the flange is not provided in a toe-side region and a heel-side region,
the flange is joined to the body member; and
a thickness T 2 of the second flange is smaller than a thickness T 1 of the first flange.

9. The golf club head according to claim 8 , wherein the thickness T 1 is equal to or greater than 0.5 mm and equal to or less than 2.0 mm.

10. The golf club head according to claim 4 , wherein the thickness T 2 is equal to or greater than 0.5 mm and equal to or less than 2.0 mm.

11. A golf club head comprising:
a face member formed by casting; and
a body member having an opening on a hitting surface side,

wherein:
the opening of the body member is covered by the face member;
the face member includes a flat plate portion forming the hitting surface, and a flange extending backward from a peripheral edge of the flat plate portion;
the flange includes a first flange located in a top-side region, and a second flange located in a sole-side region;
the flange is not provided in a toe-side region and a heel-side region,
the flange is joined to the body member,
the face member has a plurality of score lines,
the score lines include a longest score line, and
if a length of the first flange is represented by L 1 , and a length of the longest score line is represented by L 3 , then L 1 /L 3 is equal to or greater than 0.7 and equal to or less than 1.2.

12. A golf club head wherein comprising:
a face member formed by casting; and
a body member having an opening on a hitting surface side,

wherein:
the opening of the body member is covered by the face member;
the face member includes a flat plate portion forming the hitting surface, and a flange extending backward from a peripheral edge of the flat plate portion;
the flange includes a first flange located in a top-side region, and a second flange located in a sole-side region;
the flange is not provided in a toe-side region and a heel-side region,
the flange is joined to the body member,
the face member has a plurality of score lines,
the score lines include a longest score line, and
if a length of the second flange is represented by L 2 , and a length of the longest score line is represented by L 3 , then L 2 /L 3 is equal to or greater than 0.7 and equal to or less than 1.2.
