Abstract
A golf club head comprises a head main body and a face member. The head main body is provided with a face support portion to which the face member is fixed. The face member comprises a front plate portion, a backwardly directed portion extending backwardly of the head from the front plate portion, and a centrally directed portion extending toward of a center of the face from the backwardly directed portion. The rear surface of the centrally directed portion is fixed to the face support portion of the head main body.
Claims18
A golf club head comprising a head main body and a face member, wherein
- the head main body is provided, on a front side of the head main body, with a face support surface to which the face member is fixed, and which has a width W1 when measured inwardly from an outer peripheral surface of the head main body, orthogonally to the outer peripheral surface of the head main body, and
- the face member comprises:
- a front plate portion having a front surface that forms at least a part of a surface for hitting a ball;
- a backwardly directed first portion extending backwardly of the head main body from the front plate portion to form an outer peripheral surface on a back side of the face member:
- and
- a centrally directed second portion extending from the backwardly directed first portion, inwardly towards a plane oriented perpendicular to the face member and intersecting the face member center to have an inner peripheral edge, and to have a width W2 when measured orthogonally to the outer peripheral surface of the face member from the outer peripheral surface of the face member to the inner peripheral edge, wherein a rear surface of the centrally directed second portion is fixed to the face support surface of the head main body, wherein the rear surface of the centrally directed second portion is provided with a protrusion projecting to a rear of the head, and the face support surface is provided with a recess for fitting the protrusion, and wherein
- the width W2 of the centrally directed second portion is larger than the width W1 of the face support surface.
An iron golf club head comprising a head main body and a face member, wherein
- the head main body is provided, on a front side of the head main body, with a face support surface to which the face member is fixed, and which has a width W1 when measured inwardly from an outer peripheral surface of the head main body, orthogonally to the outer peripheral surface of the head main body, and
- the face member comprises:
- a front plate portion of which a front surface forms at least a part of a surface for hitting a ball;
- a first portion extending backwardly of the head from the front plate portion to form an outer peripheral surface of the face member;
- and
- a second portion extending from the backwardly directed first portion, inwardly towards a plane oriented perpendicular to the face member and intersecting the face member center to have an inner peripheral edge, and to have a width W2 when measured orthogonally to the outer peripheral surface of the face member from the outer peripheral surface of the face member to the inner peripheral edge, wherein
- a thickness of the first portion is in a range from 0.5 to 4.0 mm,
- the second portion extends along the rear surface of the front plate portion while keeping a distance L in a range from 0.5 mm to 4.0 mm between a rear surface of the front plate portion and a front surface of the second portion,
- a minimum thickness t2 of the second portion measured perpendicularly to the front surface of the front plate portion is in a range from than 0.5 mm to 2.5 mm,
- the width W2 of the second portion is larger than the width W1 of the face support surface, and
- a rear surface of the second portion is contacted with and fixed to the face support surface of the head main body, and
- wherein
- the head main body comprises a peripheral weight portion spaced apart from the rear surface of the second portion toward a rear of the head, and
- wherein the rear surface of the second portion is provided with a protrusion projecting to the rear of the head, and the face support surface is provided with a recess for fitting the protrusion, and
- in a direction orthogonal to the outer peripheral surface of the face member, the peripheral weight portion extends inwardly beyond said inner peripheral edge of the second portion.
