PROBLEM TO BE SOLVED: To provide an injection molding machine or the like, within which a lubricating oil can be automatically fed with no need of its periodical exchanging work. SOLUTION: The injection molding machine has an injection driving device 20 having an inner space 20a, within which a shaft (not shown) for turning a screw (not shown) is housed under the state being supported by a bearing (not shown), and at least one driving part (not shown) to be driven by the pressure of a hydraulic oil. Further, the injection molding machine is equipped with a hose (not shown) for feeding some part of the hydraulic oil as the lubricating oil in the inner space 20a. Furthermore, in the injection driving device 20, a discharging port 14 for discharging the portion exceeding a certain amount of the hydraulic oil outside the inner space 20a under the condition that the amount of the hydraulic oil in the inner space 20a exceeds the certain amount is provided.
