A tennis swing exercising device is provided to enable a user to do necessary swing exercise by him/herself without the help of a partner repeatedly by letting the hit tennis ball returned in a predetermined direction. A tennis swing exercising device includes a support(10), a court body(20), an upper coat(C2), a moving path, and a tennis ball returning portion(30). A court(C1) is fixed on a court support frame(21) with plural elastic members(25) in the court body. The upper court is fixed to the court support frame on the upper part of the court with plural elastic members. The moving path is formed by the court and the upper court. The tennis ball returning portion is disposed on the upper court, and comprises a sealed space, which communicates with the upper end portion of the moving path and has an open portion(32).
