。 A motor, a pressing means that operates in response to the rotational force of the motor, a first clutch member that rotates in response to the rotational force of the motor, and a clutch that moves by the operation of the pressing means and engages with the first clutch member. a second clutch member that engages, a transmission gear that transmits the rotational force of the motor in response to rotation of the second clutch member, and operates by receiving the rotational force of the motor via the transmission gear, and a drive means that provides a restoring force in the opposite direction to the rotational force, and a shutter that is opened and closed by the drive means,
A shutter drive device characterized in that the force by which the first and second clutch members tend to engage due to the pressing means is set to be greater than the force by which the two clutch members tend to separate due to the restoring force.
