However, the improvement in the average life expectancy is largely due to the recent rise in health orientation along with the improvement in eating habits. Exercise contributes easily to health and health.

[0003] In recent years, such exercises include golf and the like. However, baseball has been popularly used as a civil exercise from so-called grass baseball to professional baseball for general amateurs and adolescents. However, in baseball, not only pitchers (pitchers) but also baseball players cannot always miss pitching practice so that accurate pitching can be performed. Therefore, amateur players who play the baseball For a professional player, the pitching practice is indispensable, and the skill improvement is realized by repeating the pitching practice.

[0004] Conventionally, as the pitching practice tool, as shown in FIG.
A practice method has been generally practiced in which a player swings a ball down like a ball.

In the pitching practice mode in which the towel 2 of the conventional mode is gripped by the hand 1 and swung down as if it were a ball, the fingertips and wrists need to be “Straight ball”, “curve”, “slider”, “fork”, “knuckle” that throws a ball by technically dexterously using twisting or bending.
There was a feeling that a delicate twist on the changing ball could not be obtained.

[0006] That is, it is impossible to practice to master the position of releasing the ball from the fingertip which is important for the control to be performed when the arm swung up in the pitching motion is swung down.

Also, in pitching practice in which the ball is thrown down using the seed towel 2, since "legume" and "octopus" which are important for the pitcher generated when releasing the ball from the fingertip are not formed, the fingertip does not harden physiologically and the speed ball There was a neck that couldn't practice throwing a ball with long stretch.

To cope with this, one of the applicants disclosed in Japanese Patent Application Laid-Open No. 8-26697 (Japanese Patent Application No. 7-97971),
