The size of the iron club head is increased, the weight of the head is distributed to the periphery, the moment of inertia is increased, and the face surface is enlarged to reduce the damage, and the utility club has an intermediate shape between the wood club and the iron club. Attempts have been made to replace the club with a low center of gravity of the head and a club located at the back of the face to make it easier to raise the ball, but in the former, the direction of the ball is somewhat improved. However, it is not enough to raise the hitting ball enough to give a satisfactory flight distance, and the latter has a disadvantage that it is difficult to hit when encountering a scene where the ball is in a severe rough, etc. At present, the problem of the difficulty of striking iron clubs from long to long has not been solved.

捕らえ易いことから強い打球を得ることが出来て、飛距
離の増大が得られる。In the golf club head according to the present invention configured as described above, the center of gravity of the head is extremely low and the center of gravity of the head is relatively low with respect to the striking surface (that is, the face surface) while maintaining the shape of a normal iron club. Because it can be set deep behind, even a golf player of ordinary skill can easily hit a ball with a high ballistic trajectory and a wide sweet area on the face surface and a core on the face surface , It is possible to obtain a strong hit ball and increase the flight distance.

果、飛距離のバラツキが低減する。Further, since the heavy back wall portion is disposed at a distance behind the face surface via the hollow portion, the center of gravity of the head is extremely deep as compared with a normal iron club, and the center of gravity of the head passes through the center of gravity of the head. As a result, the moment of inertia about the horizontal axis increases, so that a stable loft angle (a so-called effective loft angle) at the time of hitting the ball can be obtained. As a result, variations in the flight distance are reduced.

からヘッドの重心位置を深くする効果が得られる。The width of the cavity formed by being surrounded by the ball striking portion, the sole portion, the back wall, and the like at the lower portion of the back surface of the ball striking surface, which is parallel to the striking direction (the front-rear direction), is narrower at the upper side of the cavity portion and lower. It is preferably formed wide on the side. By making the cavity part like this, the sole part or a part of the sole part molded separately from the head main body is easily inserted into the head main body from the sole side, and the back wall part has its top part. Is moved forward and the bottom is moved rearward to be inclined, so that the effect of deepening the position of the center of gravity of the head can be obtained.

する効果が得られる。According to a fifth aspect of the present invention, when the thickness of the back wall portion is set to be thicker at the toe side portion than at the center of the hitting surface, the moment of inertia on the toe side increases. The head easily returns during a swing, so that the so-called slice trajectory of the hit ball is corrected. Conversely, when the heel side portion is set thick, the so-called hook trajectory of the hit ball is corrected. In addition, when the toe side and the heel side are both thick, distortion of the face surface at the time of hitting the ball is extremely small, and an effect of reducing hitting damage can be obtained.
