1. A golf club head, comprising:
- a face plate formed from metal;
a crown formed from fiber reinforced plastic attached to the face plate, wherein the crown includes a low rigidity portion extending from a vicinity of the face plate toward a rearmost portion of the golf club head, wherein the low rigidity portion has a width that becomes gradually narrower as it extends toward the rearmost portion, wherein the low rigidity portion is formed between a first high rigidity portion located adjacent a first side of the low rigidity portion and a second high rigidity portion located adjacent a second side of the low rigidity portion, and wherein the low rigidity portion has a lower rigidity than the first high rigidity portion and the second high rigidity portion;
a sole formed from fiber reinforced plastic attached to the face plate and the crown; and
a weighted member provided inside a space defined by the crown, sole, and face plate, wherein the weighted member is provided at the rearmost portion of the golf club head.

Abstract
A golf club head enables the initial velocity of a ball to be increased and enables the carry to be lengthened. In some example structures, the golf club includes a face plate formed from metal and club head body (e.g., a crown and sole) formed from fiber reinforced plastic. A weighted body is provided inside the rearmost portion of the golf club head and a low rigidity portion whose width becomes gradually narrower as it approaches the rearmost portion is provided in the crown extending from the vicinity of the face plate to the rearmost portion.

17. A golf club head, comprising:
-
a face plate; a club head body attached to the face plate, wherein the club head body includes a deformation wave transmitting system for transmitting at least a portion of the energy contained in a deformation wave generated when a ball is struck by the golf club head away from and toward the face plate, wherein the deformation wave transmitting system includes a low rigidity portion extending from a vicinity of the face plate toward a rearmost portion of the golf club head, wherein the low rigidity portion has a width that becomes gradually narrower as it extends toward the rearmost portion wherein the low rigidity portion is formed between a first high rigidity portion located adjacent a first side of the low rigidity portion and a second high rigidity portion located adjacent a second side of the low rigidity portion, and wherein the low rigidity portion has a lower rigidity than the first high rigidity portion and the second high rigidity portion; and a reflecting member for reflecting at least a portion of the energy of the deformation wave incident thereon back to the face plate via the deformation wave transmitting system. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A golf club head, comprising:
-
a face plate formed from metal; a crown formed from fiber reinforced plastic attached to the face plate, wherein the crown includes a low rigidity portion extending from a vicinity of the face plate toward a rearmost portion of the golf club head, wherein the low rigidity portion has a width that becomes gradually narrower as it extends toward the rearmost portion, wherein the low rigidity portion is provided on a convex portion of the crown so as to protrude from a main surface of the crown; a sole formed from fiber reinforced plastic attached to the face plate and the crown; and a weighted member provided inside a space defined by the crown, sole, and face plate, wherein the weighted member is provided at the rearmost portion of the golf club head. - View Dependent Claims (33, 34)
