  • Publication number: 20020016230
    Abstract: A sweet spot 3 of an impact portion 2 has a smaller diameter than the other portions of the impact portion 2, whereby the impact portion 2 has an intermediate tapering shape in the longitudinal direction. Thus, even if hit with a portion at some distance from the sweet spot, rebound performance is not significantly reduced. Therefore, a bat having a large sweet area and capable of reducing the occurrence of foul balls is obtained.
