PROBLEM TO BE SOLVED: To provide an entertaining capability so as to train fingers enjoyably by arranging a counter, which integrates and displays the number of reciprocation of a plunger, in a finger training apparatus in which the plunger is reciprocated by a predetermined distance against loading springs. SOLUTION: A bottom plate of a body 12 in a finger training apparatus is placed on a palm and four fingers excepting a thumb are hooked on four finger hanging recesses 72a-72d, and then, pressing force is applied in the direction of the body 12 to the apparatus by the fingers until a handle 71 is stopped, so that the fingers are trained. When application of force by the fingers is loosened, the handle 71 is returned to the original position by means of restoring force of loading springs 73. In the finger training apparatus 1 constituted in this way, a counter 2 is incorporated so as to count the number of reciprocation of the handle 71, and the counted result is represented through a display window 6 provided with a liquid crystal display panel 7 which can display a four-digit number. Alternatively, a condition corresponding to the reciprocating motion may be displayed graphically. In addition, consumed energy is converted into electric power so as to be used as an electric power source for the display means. |
