PURPOSE: To improve the drive of an electrically driven member where the danger of an object or body portion being caught therein is present.

CONSTITUTION: The drive of an electrically driven member where the danger of an object or body portion being caught therein is present is provided with a means 18 for detecting a characteristic amount showing a standard measure for the operating force of a member 15, a signal processing device 11 which detects, from the characteristic amount, a standard measure for interruption of an electric motor 10 or for reversal of rotating direction, and at least one temperature sensor 19 for detecting temperature generated at the electric motor 10, the signal processing device 11 controlling the characteristic amount depending on the temperature detected.
