Pitching training tool with indicator
First Claim
1. A baseball pitching training tool comprising:
- a rod-shaped body portion having a hollow cylindrical shaft portion that is of a lighter weight than a regulation ball and a gripping portion integrally formed at one end of the shaft portion, said gripping portion having one end formed as a grip having a diameter larger than that of said rod-shaped body portion;
a detector, which is incorporated in said gripping portion side of the rod-shaped body portion and which detects a state of motion when the rod-shaped body portion is swung around;
an arithmetic processing portion, which is disposed on the gripping portion side of said rod-shaped body and which performs computations based on motion state data from said detector; and
a display disposed on the gripping portion side of the rod-shaped body and displays the results of computations by said arithmetic processing portion, the weight of the pitching training tool being lighter than a regulation baseball.
