PROBLEM TO BE SOLVED: To reduce the total length of an injection molding machine using a built-in motor as an electric servomotor for measuring. SOLUTION: The built-in motor with a hollow interior portion possessing a cylindrical stator and a cylindrical rotator positioned inside the stator is used for the electric motor for measuring. A sleeve is fixed in the rotator of the built-in motor. A member fixing a rear-end portion of a screw is connected to and fixed in the sleeve, and a nut being a direct moving part of a ball screw mechanism to convert a rotary motion into a straight-line motion of an electric motor for injecting is also connected to and fixed in the sleeve.
