PROBLEM TO BE SOLVED: To provide an injection molding machine that allows easy adjustment of a phase difference between rotational directions of respective belts rotating in synchronization with each other.SOLUTION: An injection molding machine comprises: a first phase difference adjustment pulley 12 wound by a first belt 20 wound on a first drive pulley 7 and first drive transmission pulley 10; and a second phase difference adjustment pulley 13 wound by a second belt 21 wound on a second drive pulley 9 and second drive transmission pulley 11. The first phase difference adjustment pulley 12 and the second phase difference adjustment pulley 13 are provided concentrically with each other so as to be independently rotatable. Fastening means is provided which locks the first phase difference adjustment pulley 12 and the second phase difference adjustment pulley 13 integrally with each other. Consequently, the first phase difference adjustment pulley 12 and the second phase difference adjustment pulley 13 are unlocked to allow easy adjustment of a phase difference between rotational directions of a first belt 20 and a second belt 21. |
