Golf club head and golf club

1. A golf club head having a hollow portion therein, including: a crown portion forming a top surface of the head; a resin member composed of a fiber reinforced resin forming said crown portion at least partially; a reinforcing member attached to said resin member, and made of a material having higher rigidity than that of the fiber reinforced resin forming the resin member; said reinforcing member integrally comprising a plate-like portion which is embedded in the resin member and extends along a plane direction of the resin member, and a rib protruding from the plate-like portion toward the hollow portion, wherein the reinforcing member has a T-shaped in a cross section orthogonal to a longitudinal direction thereof.

2. The golf club head according to claim 1 , wherein the reinforcing member extends in a front-back direction of the head.

3. The golf club head according to claim 1 , wherein

the reinforcing member extends in a toe-heel direction of the head.

4. The golf club head according to claim 1 , wherein

at least a part of the reinforcing member is composed of a metal material.

5. The golf club head according to claim 1 , wherein

at least a part of the reinforcing member is composed of a fiber reinforced resin.

6. The golf club head according to claim 1 , wherein

a through-hole is provided in the rib.

7. The golf club head according to claim 1 , wherein

the resin member includes a matrix resin and a reinforcing fiber reinforcing the matrix resin, and

the reinforcing fiber comprises an outer reinforcing portion disposed on the outside of the plate-like portion and an inner reinforcing portion disposed on the inside of the plate-like portion.

8. The golf club head according to claim 1 , wherein

the plate-like portion of the reinforcing member is formed of a fiber reinforced resin.

9. The golf club head according to claim 1 , wherein

the reinforcing member is formed of same fiber reinforced resin as that of the resin member.

10. The golf club head according to claim 1 , wherein

the reinforcing member is formed of a fiber reinforced resin,

a matrix resin of the fiber reinforced resin of the reinforcing member is same as a matrix resin of the resin member, and

a modulus of elasticity of a reinforcing fiber of a reinforcing member is larger than a modulus of elasticity of a reinforcing fiber of the resin member.

11. The golf club head according to claim 2 , further including: a sole portion constituting a bottom surface of the head and a side portion arranged between the sole portion and the crown portion, wherein the reinforcing member is continuously provided from the crown portion to the sole portion through the side portion.

12. The golf club head according to claim 1 , wherein

a length of the reinforcing member is not less than 150 mm.

13. The golf club head according to claim 1 , wherein

in a plan view of a standard state in which the head is grounded on a horizontal plane HP with a centerline of a shaft axis of the head being disposed in a vertical plane and inclined at a specified lie angle, and a face of the head being held at a loft angle β,

the reinforcing member is disposed on a center of gravity of the head.

14. The golf club head according to claim 1 , wherein

a through-hole is provided in the rib, and

a total area Sk of the through-hole is 30 to 50% of an area Sb of a lateral face of the rib in the case in which the through-hole K is not provided.

15. The golf club head according to claim 1 , wherein

the plate-like portion is formed of a fiber reinforced resin and the rib is formed of a metal material.

16. The golf club head according to claim 1 , wherein

the reinforcing member has a plurality of the ribs provided in one plate-like portion.

17. The golf club head according to claim 1 , wherein

a thickness of the rib varies in a length direction of the reinforcing member.

18. The golf club head according to claim 1 , further comprising a golf club shaft.
