1. A tennis training apparatus comprising:
a sheet supporting frame comprising a left frame structure and a right frame structure, each at an incline from a front to a back; a hit ball receiving sheet comprising a bottom edge and a top edge, the hit ball receiving sheet supported between the left frame structure and the right frame structure so as to slope from the bottom edge to the top edge with a horizontal fold between the bottom edge and the top edge; and a returning guide portion provided at an upper end of the hit ball receiving sheet in an eave shape curved toward a near side when viewed from the side, wherein due to the eave shape the top edge of the hit ball receiving sheet is not a highest point of the hit ball receiving sheet; and a first guiding structure between the fold and the bottom edge formed in such a manner as to smoothly curve without having any angular portion, whereby a player is able to select from one or more returning positions by changing an angle between the fold and the bottom edge, wherein a hit ball hit by the player is received by the hit ball receiving sheet, the hit ball moves upward along the hit ball receiving sheet and is then returned by the returning guide portion to move downward along the hit ball receiving sheet to the first guiding structure to fly out of the first guiding structure as a returned ball, wherein the returned ball bounces on a base face of a training place to return again to near the player, and the returned ball is hit back by the player to the hit ball receiving sheet to continue a training. |
