PROBLEM TO BE SOLVED: To solve such the problem of the conventional vertical rotation type golf training machine that it is hard for a user to completely check whether or not the user swings a club in a square face angle since the quantity of deviation at the start of rotation is small even when swing of slightly slicing or slightly hooking is made, and this is caused since the hitting part has a spherical shape and it is impossible to take a distance between an action line of force in parallel with the ball flying direction passing the hitting point and the center of the hitting part large enough, and thus, the quantity of deviation can not be made noticeable. SOLUTION: The hitting part of the vertical rotation type golf training machine is formed of a plurality of disk shape matters and a matter capable of adjusting a space therebetween. Accordingly, the distance between the action line of force in parallel with the ball flying direction passing the hitting point and the center of the hitting part can be taken large, thus the quantity of deviation is made noticeable, and the effect of training in a square swing can be improved by verifying those.
