持されていることを特徴とするピッチングマシン。In a pitching machine in which a pair of upper and lower elastic wheels are rotated in opposite directions and a ball is pitched forward between the two elastic wheels, both left and right ends of the rotating shaft of the lower elastic wheel are supported, respectively. The fixed support plates on both the left and right sides are connected by a connecting rod and can be fixed to the frame of the pitching machine, and the adjustable support plates on both the left and right sides, which respectively support the left and right ends of the rotating shaft of the upper elastic wheel, are connected by a connecting rod and fixed to the frame of the pitching machine. It is pivoted to the frame of the pitching machine with a pivot that passes through the rear end parallel to the rotation axis, and a positioning rod that passes through the front end parallel to the rotation axis is vertically attached to the frame so that it can be adjusted up and down. A pitching machine characterized by being held between a lower end surface of a bolt and an upper end surface of a lower bolt.
