Abstract

A head 2 includes: a face member fc1 having a hitting surface 4; and a body member bd1 having a hosel 6, a sole surface 8, and a toe-side surface 9. The face member fc1 further has a top-side flange FL1 including a top surface 5. The body member bd1 has a hosel-forming part 24 including the hosel 6, a sole-forming part 28 including the sole surface 8, and a toe-forming part 26 including the toe-side surface 9. The hosel-forming part 24 has a heel joint portion Jh joined to a heel-side end of the top-side flange FL1. The toe-forming part 26 has a toe joint portion Jt joined to a toe-side end of the top-side flange FL1. A body missing portion ms1 in which the body member bd1 is not present is provided between the toe joint portion Jt and the heel joint portion Jh.

First claim

What is claimed is:

1. A golf club head comprising: a top surface; a hitting surface; a sole surface; a toe-side surface; and a hosel, wherein
the golf club head includes: a face member having the hitting surface which includes a face center; and a body member having the hosel, the sole surface, and the toe-side surface,
the face member further includes a top-side flange including the top surface,
the body member includes a hosel-forming part including the hosel, a sole-forming part including the sole surface, a toe-forming part including the toe-side surface, a central opening and a body gap structure in which a part of a frame surrounding the central opening periphery is absent,
the hosel-forming part includes a heel joint portion joined to a heel-side end of the top-side flange,
the toe-forming part includes a toe joint portion joined to a toe-side end of the top-side flange,
a body gap portion in which the body member is absent is provided between the toe joint portion and the heel joint portion, and
the top-side flange occupies the body gap portion so as to make the frame continuous.

2. The golf club head according to claim 1 , wherein the body gap portion is disposed at a position in a toe-heel direction which is the same as that of the face center.

3. The golf club head according to claim 1 , wherein the body gap portion is disposed at a toe side with respect to the face center.

4. The golf club head according to claim 1 , wherein the body gap portion is disposed at a heel side with respect to the face center.

5. The golf club head according to claim 1 , wherein the face member further comprises sole-side flange including the sole surface.
