Abstract
A golf club comprising a head having a neck portion, a shaft having a distal end portion attached to the neck portion, and a neck neighboring portion extending above the neck portion at which the shaft is dynamically bent due to an impact of the head with a golf ball during a swing of the golf club. A member is provided in the shaft for increasing a response to the impact. For example, materials having a high elastic modulus under impact is inserted or a section modulus of the shaft is rearranged in the bendable portion. Accordingly, a lower portion of the shaft is initially bent backward relative to the remaining portion of the shaft and then is moved rapidly forward to cause the head to advance while in contact with the golf ball.
