Abstract: When a main switch (82) is in an on-state, a controller (80) allows an electric motor (41) to drive a sliding door to open and close an opening, and when the main switch (82) is in an off-state and a half latch switch (66) is in an on-state, the controller (80) performs a braking control to allow the electric motor (41) to generate a braking force. When the main switch (82) is in the on-state, the sliding door can be opened and closed automatically. When the main switch (82) is in the off-state and the sliding door is closed manually, the improperly-closed state detecting switch is switched on before a full-latch state, the controller performs a braking control of the driving source. In this manner, damage to components caused by the inertial force of the driving source which results from an abrupt stop of the opening and closing unit can be certainly prevented without enhancing the rigidity of a casing, etc.
