A manual/automatic driving unit is provided to reduce size and to prevent torque from being transmitted to an operating unit by controlling torque using a power control unit. A manual/automatic driving unit comprises a guide, an input unit, an output unit, a moving unit, an operating unit, a power control unit(11), a mechanical two-way clutch, and a mechanical control unit. The input unit is moved on the moving unit by inputted torque, and transmits torque to the moving unit. The output unit is rotated on one of a frame or the moving unit. The operating unit supplies electric torque to the driving unit. The power control unit controls the diving torque. There is a predetermined gap between the output unit and the power control unit. The mechanical two-way clutch prevents rotation of the output unit at two sides, when torque is not inputted from the input unit or the operating unit. The mechanical control unit has an unlocking unit to release locking state of one side of the driving unit when torque is inputted from the operating unit or the input unit. The moving unit is moved by torque received from the operating unit or the input unit. The mechanical control unit has an inner wheel, an outer wheel, a space, a stopping member, an output unit, a two-way locking unit, and a releasing unit. The inner and the outer wheels are aligned on the same shaft. The two-way locking unit locks a circumferential surface and a cam surface to prevent two-way rotation of the output unit. The releasing unit is operated by the mechanical control unit. |
