PURPOSE: To provide a stroke end stopping circuit of a DC servo motor which can safely and surely stop and reset the DC servo motor in a simple constitution when the servo motor exceeds its shift limit.

CONSTITUTION: A DC servo motor 3 is provided as a drive source of a mobile object together with the limit switches 5 and 6 which detects the shift limit of the mobile object, and a controller 1 which performs the drive control of the motor 3. Furthermore, the diodes 2 and 4 are connected in parallel to the normally-closed contacts 5a and 6a of switches 5 and 6 to supply the drive output of the motor 3 to this motor from the controller 1 via the contacts 5a and 6a and also to supply a current to the motor 3 to revolve the motor 3 in the direction opposite to the prescribed direction when the motor 3 revolves in the prescribed direction to actuate the switches 5 and 6 and the contacts 5a and 6a are opened.
