The elastic member 7 positioned between the metal plate 6 and the striking member 1 is compressed and bent by the pressure at the time of collision with the striking member 1 upon impact. On the other hand, since the bending of the elastic member 7 and the diameter of the hole 8 are larger than the outer diameter of the engaging member 9, the play member 9 forms a play to enable the elastic member 7 to effectively perform the function of cushioning. The elastic material 7 is effectively expanded and contracted, and the struck member 1 is moved up and down to absorb shocks and vibrations generated by the hitting action trainer of the present invention when the impact is suppressed. The shape of the hole 8 at this time may be any shape such as a circular shape or an elliptical shape.

As shown in FIGS. 4 and 5, the cushioning material 7 is attached between the metal plate 6 and the struck member 1, and the diameter of the hole 8 is larger than the outer diameter of the engaging member 9, and the engaging member is formed. When a play is formed around the periphery of the 9 to make the shaft 3 non-fixed, the cushioning material 7 shown in Figs. 4 and 5 is not mounted, and a comparative test is performed in which the play is not formed around the engaging member 9. The test method is to mount each hitting action trainer on a rotating plate having a diameter of 57 cm and rotate it by 360 degrees so that the striking member 2 is in conflict with the struck member 1 to apply its load.

The total length of each hitting action trainer for the comparative test was 90 cm, and the weight of the moving striking member 2 was also 2 kg, respectively. The grip portion 4 is attached to the rotating plate, and the hitting action trainer is also rotated together with the rotating plate to naturally fall when the striking member 2 just reaches the clock point 12, and the striking member 2 is attached when the striking action is mounted. It collides with the struck member 1. The comparison of the respective durability degrees when the number of revolutions is 0.17 rotations per second and the average head speed is 5.96 m per second is as shown in the following paragraph.

As is apparent from the table below, when the fixed engagement member 9 is confirmed, the number of rotations of the rotary plate is significantly different when the engagement member 9 is not fixed. When the baffle plate 7 was attached and the engaging member 9 was not fixed, no abnormality was observed and the rotating plate was rotated for less than 40 days, and 537 and 150 times were stopped. On the other hand, when the cushioning material 7 is not attached and the engaging member is fixed, the engaging member is broken about 3 days, and the rotating plate is stopped 25 or 550 times.
