ングを行うだけで自然に方向性が安定する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club for stabilizing the direction of a shot. 2. Description of the Related Art In conventional golf clubs, many years of skill have been required to return a wrist at the moment of hitting a ball, in order to fly the ball accurately in a target direction. Also, in the case of an iron shot of a deep rough, the head was turned back by the grass getting stuck in the shaft, and the direction of the face was sometimes out of order. [0003] If a club is swung in a target direction without special skill, the ball naturally flies in a target direction. Means for Solving the Problems (a) The center of gravity (5) of the head and a sweet spot (the intersection of the face with a perpendicular drawn from the center of gravity to the face (3))
The straight line (AA) passing through (6) intersects with the extended line (BB) of the shaft axis. (B) The intersection (7) of (a) is located ahead (target direction) of the center of gravity (5) of the head. (C) A vertical plane including an extension line (BB) of the shaft axis intersects at right angles with a vertical plane including a straight line (AA) passing through the center of gravity (5) of the head and the sweet spot (6). [0005] In the golf club of the present invention, by swinging the club while accelerating the head toward the target direction, the center of gravity (5) of the head is pulled to the point 7 while its orbit is The face naturally turns to the target direction by swinging so as not to oppose the force because the force to move to follow the force acts. Also, even in the case of an iron shot of a deep rough, the direction is stabilized without the grass getting stuck in the shaft and only the head returning. At point 7, the force for stabilizing the direction increases as the distance from the center of gravity (5) of the head increases. According to the structure of the club of the present invention, the direction is naturally stabilized only by performing a swing.
