PROBLEM TO BE SOLVED: To provide an injection molding machine in which a grease tray member is made to have a tiltable structure so that waste grease can be recovered easily and surely even when the injection molding machine has no space enough to pull out the grease tray member. SOLUTION: A mold clamping unit 1 on a machine base 3 includes a fixed plate 4 arranged fixedly on the machine base 3, a pressure receiving plate 6 and a movable plate 5. The pressure receiving plate 6 includes: an electric servomotor 8; a ball screw mechanism 9 which is used for converting rotary motion into linear motion and includes a nut and a screw shaft; and a toggle link mechanism 10 to which the axial-direction driving force of the ball screw mechanism is transmitted through a crosshead 11 and which drives the movable plate to be moved forward or backward. The grease tray member 12 is disposed in the machine base in the lower part of an upper frame part including an upper frame longitudinal member 13 and an upper frame lateral member 14 and below the toggle link mechanism of the mold clamping unit and below the movable part of the movable plate 5. The grease tray member can be turned around the central axis engaged with a metal plate 17 from a horizontal state thereof to a position of another metal plate 18, which position is set as a limit.
