PROBLEM TO BE SOLVED: To automatically adjust a load balance of a turning force transfer unit. SOLUTION: This injection molding machine comprises: a driving part; a plurality of rotary drive units which are equipped with a motion direction conversion parts; a turning force transfer unit which is equipped with driving-side and driven-side rotational members for use in synchronization, arranged in the rotary driving unit; and a reaction imparting part which establishes connections among respective conversion elements arranged in the state of being permitted to rotate and which imparts reaction to each of the conversion elements, in each of the motion direction conversion part. In this case, in each of the motion direction conversion part, since the respective conversion elements, which are arranged in the state of being permitted to rotate, are connected together by means of the reaction imparting part, the load balance of the turning force transfer unit can be automatically adjusted by the rotation of the respective conversion elements, even if the load balance is disrupted due to any cause.
