PROBLEM TO BE SOLVED: To provide a motor driving control circuit for driving a motor under control accurately without erroneous operation. SOLUTION: A motor driving control circuit includes a lead relay (L) or the lead relay (L) and a relay circuit, in which a first driving coil LC1 attains a sensitive level through a lock current generated at a locked state of a motor (M) to change a relay switch LS and short-circuit a motor (M) circuit or an excitation coil (RC) circuit. In this way, the locked state of the motor (M) is detected by the relay circuit, and the continuity of the motor (M) is broken on the basis of the detected result of the lead relay (L) only by the lead relay (L) or by the lead relay (L) and the relay circuit. As a result, the rocked state can be judged accurately without instability as compared with current control using an electronic part, and the driving control of the motor (M) can be carried out surely.
