Abstract
A state of a head placed such that its shaft axis is vertical to a horizontal plane and a face normal line is parallel to a perpendicular plane on which the shaft axis lies is defined as a 0-degree state. A direction parallel to the perpendicular plane and parallel to the horizontal plane is defined as a projection direction. A projected area of the head projected in the projection direction when the head is rotated by θ° about the shaft axis toward a back side from the 0-degree state is denoted by WAθ. WAθ is divided by the shaft axis into an area Afθ and an area Abθ. Airflow causes a force acting on the area Afθ in a face-closing direction and a force acting on the area Abθ in a face-opening direction. (Af−Ab) is −4500 (mm) or less. (Af−Ab) is 4700 (mm) or less.
