Abstract: The present invention relates to a pitching machine. According to the present invention, an upper wheel (13) and a lower wheel (14) are disposed such that motors (11) and (12) are each disposed on a central shaft on one surface and a ball is pitched using the rotation driven by the motor. A ball supply container (15) and a ball supply device (16) are disposed on one side of the upper wheel (13) and lower wheel (14) so as to supply the ball to the upper and lower wheels. A stepper motor (18) is connected to the central shaft of the upper wheel (13) and lower wheel (14) so as to adjust the directional angle of the upper and lower wheels according to the angular direction of the ball. A body rod (20) supporting one side of the upper and lower wheels, the stepper motor (18), and the ball supply container (15) are connected to a triangular supporting leg (21) at the lower portion so as to support the body rod (20).
