GEAR DEVICE, INSTALLING METHOD AND INSTALLING DEVICE OF GEAR IN THIS GEAR DEVICE

摘要

PROBLEM TO BE SOLVED: To easily and surely provide a highly accurate gear device for easily and accurately installing a plurality of gears on an installing base so that an origin position of movable bodies matches to an output shaft of a step motor, and bilaterally symmetrically and accurately controlling an angle of the two movable bodies. SOLUTION: This gear device connects the movable bodies possessed by a game part for a Pachinko machine and the output shaft of the step motor, and has the plurality of gears 1 to 4 and the installing base 5 for rotatably supporting these gears. The gears 1 to 4 form an origin positioning hole 10 for matching a movable origin position of the movable bodies to a driving origin position of the output shaft of the step motor. The installing base 5 forms a plurality of positioning work holes 12 for inserting-extracting a plurality of positioning work bars 11 for determining an installing position of the gears by being inserted into the origin positioning hole of the gears.
