PROBLEM TO BE SOLVED: To provide a driving apparatus for injection molding machine of which the assembling is facilitated by simplifying the constitution of the apparatus, which is made possible to stably transfer power, and further, can be reduced in cost by constituting itself with easily fabricable parts. SOLUTION: In the driving apparatus A for injection molding machine provided with a plurality of driving mechanisms 30 formed of a constitution in which each of transmission timing belts 16 driven by motors 8 is wound around each of transmission timing pulleys 15 attached to screw shafts 14 of ball screw mechanisms 11, and a synchronizing timing belt 21 for synchronizing the rotation of respective screw shafts 14 of the ball screw mechanisms 11; the synchronizing timing belt 21 is wound around the transmission timing pulley 15 neighboring the transmission timing belt 16, and the synchronizing belt 21 is stretched between respective transmission timing pulleys 15.
