プ部６がある。2. Description of the Related Art When a metal bat is made of an aluminum material, it is made of a hollow aluminum material as shown in FIG.
It is often the case that the grip end 2 made of an aluminum material is attached to this by welding. The main body 1
Is closed at its tip as a head portion 3, and a hitting portion 4 having substantially the same diameter is provided in the vicinity thereof, and a grip portion 6 having a small diameter is provided via a taper portion 5.

うにすることもある。In such a conventional metal bat, since the whole is a hollow body, the deformation of the ball upon hitting is large, and it is difficult for the ball to travel a long distance. Therefore, as shown in FIG. 12, a filling 7 such as a urethane foam or a urethane chip is filled in a portion of the main body 1 that is ahead of the hitting portion 4, or as shown in FIG. 13, for reinforcing the inner wall surface of the main body 1. The ribs 8 may be formed to increase the strength.

変形の回復スピードが遅いため飛距離増とはならない。However, the one in FIG. 12 is effective in reducing the amount of deformation at the time of hitting, but is not useful for increasing the recovery speed against deformation, and the one in FIG. 13 is also effective at hitting. Since the entire bat is elastically deformed and the recovery speed of the deformation is slow, the flight distance is not increased.
