To solve the problems of conventional tennis rackets that a strong swing cannot be done for reasons of safety in a case of doing a practice swing with a conventional racket in a narrow indoor space, for example, because of its long total length, and that, when using a children's racket with short total length, a swing can be done even in a small space, but a practical action to prepare for a match cannot be done because a sense of distance between both hands is different from that when using a racket for adults in a case of using the racket by gripping a grip part with one hand, and supporting a throat part with the other hand, for example, because its handle part is short as well.
In the tennis racket, the handle is formed to be as long as that of general rackets, but the length of a frame part is set shorter, so that the total length of the racket is shorter. There is no problem in practice for the shorter length of the frame part, because a ball is not hit in a practice swing.
