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 means for transmitting a deformation wave including 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;
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, the sole, and the face plate, wherein the weighted member is provided at the rearmost portion of the golf club head;
wherein the means for transmitting a deformation wave is constructed and arranged to transmit a deformation wave generated in the crown when the golf club strikes a ball along the low rigidity portion to the weighted member and back toward the face plate from the weighted member along the low rigidity portion.

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.

11. A golf club head, comprising:
-
a face plate; a club head body attached to the face plate; and a weighted reflecting member positioned at or near a rearmost portion of the club head body; and a means for transmitting a deformation wave that includes a low rigidity portion defined in the club head body, wherein the means for transmitting a deformation wave is constructed and arranged to transmit 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 the face plate to the weighted reflecting member along the low rigidity portion and back to the face plate from the weighted reflecting member along the low rigidity portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
