The rib (rb) has a sloped extending portion (ks1) which, from the heel side to the toe side, extends to approach the face. The center of gravity of the head is positioned on the heel side of the face center. The head (2) is hollow. Preferably, the sole (8) has a minimum thickness region. Preferably, the rib (rb) has a thin reinforcing section (rb2) positioned in the minimum thickness region. The rib (rb) may extend in a straight line. The rib (rb) may extend in a curve. Preferably, the sloping angle of the rib (rb) is 10°-45° relative to the toe-heel direction.</p> |
