<p>The present invention relates to a grip strength training device having an electricity-generating function that can increase the grip strength of a user hand by repeatedly clenching and opening his or her hand at the state of holding the grip strength training device in his or her hand and can also generate electricity therefrom while in use, thereby providing much excitement to him or her. When the user's hand is repeatedly clenched and opened at the state of holding the grip strength training device in his or her hand, a plurality of magnets linearly are moved into and out of a plurality of coil bobbins under the Lenz's law, thereby generating electricity therefrom, and the generated electricity can be also used as emergency power.</p> |
