The present invention relates to a training driver for increasing a long driving distance. More specifically, a hole slightly larger than a golf ball is formed on a driver face surface, so that when the training driver is accurately struck by the golf ball, the golf ball is fitted in the hole, thereby mastering the accurate striking proficiency. Also, when the impact, weight transfer, release, and follow through are properly performed, the golf ball is allowed to move in the hole that is deeply formed by an additional deeper step, thereby improving the accurate striking proficiency and increasing the long driving distance. The training driver of the present invention comprises: a club head divided into a club head face surface and a club head body; an outer diameter end formed by perforating the center region of the club head face, having a diameter of W1, and corresponding to an initial contact site of a golf ball; an inner diameter end formed by perforating the center region of the club head face, having a diameter of W2 smaller than the diameter of the outer diameter end, W1, and corresponding to a second contact site of the golf ball after the outer diameter end; and a front hole extended from the inner diameter end to have a length of H1 and formed inside the club head, wherein the front hole has a hole shape into which the golf ball is inserted having a diameter of W3. According to the present invention, in the case where a golfer uses the training driver in which the hole slightly larger than the golf ball is formed in the club head face, if the training driver is accurately struck by the golf ball, the golf ball is fitted in the hole, so that the golfer can recognize accurate striking. In order to allow the golf ball to be accurately fitted on the club face surface, the incident angle of the club face surface approaching the golf ball on the in-to-in swing path needs to advance in a straight line with the golf ball in the direct rear. Therefore, the swing training can be conducted through an accurate swing path. |
