And a lower surface that is in contact with the upper surface of the intermediate body is inclined at an angle equal to the inclination angle of the upper surface of the intermediate body with respect to the ball striking surface of the upper surface, and first driving means for rotating the intermediate body, It has a 2nd drive means which rotates a hitting table with respect to an intermediate body, It is characterized by the above-mentioned.

[0011]

In the first aspect of the present invention, since the upper surface of the batting table on the pedestal provided at the predetermined batting position is an inclined ball striking surface, the batting table is rotated at an angle of 90 degrees with respect to the pedestal. Then, the striking face can be set to a posture in which the front side or the left or right side of the striking face is inclined at a predetermined angle of elevation. Therefore, it is possible to use it as a means for improving golf by practicing by selecting the tilted posture in consideration of various ups and downs on the golf course. In the first aspect of the invention, the upper surface of the ball striking table always takes a posture inclining in any direction.

According to the fourth aspect of the invention, the direction of the ball striking surface of the ball striking table tilted by rotating the friction wheel in either forward or reverse direction can be efficiently changed by rotating the friction wheel. It can be performed quickly and well, and when a friction wheel is used, it does not bite foreign matter such as sand, so it can be driven smoothly and quietly.

Further, in the fifth invention, the upper surface of the intermediate body rotatably mounted on the pedestal is an inclined surface, and the lower surface contacting the upper surface of the intermediate body is above the ball striking surface. Since the ball striking table tilted at an angle equal to the tilt angle is rotatably mounted on the intermediate body, when the intermediate body and the ball striking table are individually rotated at any time, the upper surface of the ball striking table becomes horizontal. It can be tilted from the state to either one. Therefore, by appropriately combining and rotating the intermediate body and the ball striking table, the upper surface of the ball striking table can be inclined to the front or left or right side with respect to the ball striking direction at a predetermined high or low angle. By arbitrarily selecting each rotation angle of the hitting table, it becomes possible to incline the oblique front part with respect to the hitting direction.
