发明名称 Baseball or softball bat, bat base member and elastic sleeve
摘要 A ball-hitting portion is integrally coated with an elastic body, and thus a bat with durability that can carry the ball far can be obtained. The baseball or softball bat includes a tip portion, a ball-hitting portion, a tapered portion and a grip portion. A depression in the ball-hitting portion is integrally coated with the elastic body having a high rebound property value as a physical property. Thus, when hitting the ball, the elastic body will be compressed and deform, and energy loss due to the ball deformation will be suppressed. Moreover, the ball is carried additionally with a restoring force of the elastic body. Consequently, the bat has rebound property superior to a conventional one, and can carry the ball farther.
