Beschreibung
Zusammenfassung:	An injection molding machine includes: a movable unit; a drive unit that moves the movable unit; a transmission unit that transmits a driving force of the drive unit to the movable unit; a load detector that is provided in the transmission unit and detects a load; and a load calculation unit that calculates a load in a movement direction of the movable unit, based on a detected value of the load detector, in which the transmission unit includes a spline unit having a spline nut and a spline shaft that are connected to each other so as to be slidable in the movement direction of the movable unit, and transmit rotation, and the load calculation unit calculates the load in the movement direction of the movable unit, based on the detected value of the load detector and sliding resistance of the spline unit.
