PURPOSE: To provide a pressing machine having a displacement measuring means which can correctly measure the displacement of a slide plate engaged with a drive shaft for driving the slide plate. CONSTITUTION: The pressing machine reciprocates by a drive source between a lower support base 10 and an upper support plate 30, and has the slide plate 40 including a molding space to the lower support base. In this machine, a reference plate 90 as a displacement reference of the slide plate is supported by the lower support base. A drive source is engaged with the slide plate by a drive shaft 52 to drive to press the slide plate. A through hole is opened at the axial center of the drive shaft. The displacement measuring means 60 measures the displacement of the slide plate to the reference plate, corresponding to the hole. Thus, the displacement of the pressurizing point on the slide place can be measured.
