PURPOSE:To prevent a power window motor from being damaged, and to enable the motor to be driven by manipulating a switch even though a control device fails, by providing a relay drive circuit for energizing a first or second relay coil when a lock signal is generated and a predetermined signal is delivered from a switch manipulation detecting means. CONSTITUTION:When a power window motor 2 falls into a restrictive condition, a lock detecting means 12 detects a restraint of the power window motor 2. The lock detecting means 12 continues the issuance of the lock signal until a stand-by signal generating means 11 delivers a release signal which is generated when nether a first or a second transfer relay 3, 4 is energized. Further, a relay drive circuit 14 energizes one of the relays 3, 4 which is not the one having been driven under restraint to the power window motor 2. |
