Power swivel device

A power swivel device comprising:

• a fixing base installed in a body or a seat of a vehicle;
• a rotary plate rotatably installed on the fixing base and on which a driven gear part is formed on an inner surface or an outer surface;
• a variable actuator device which swivels and rotates the rotary plate relative to the fixing base by utilizing a drive gear engaged with the driven gear part of the rotary plate, wherein position of the drive gear is variably installed relative to the fixing base;
• and
• an elastic pressurization device configured to elastically pressurize the variable actuator device to enable the drive gear to be elastically pressurized in a direction to the driven gear part,
• wherein the variable actuator device is a rotating type variable actuator device which is rotatably installed based on swing axis installed on one side of the fixing base, and
• wherein the rotating type variable actuator device comprises:
• a rotating bracket having a portion penetrated by the swing axis to enable rotation;
• and
• an actuator installed on the rotating bracket and configured to rotate together with the rotating bracket, the actuator comprising the drive gear, a motor which rotates the drive gear, and a reduction gear box configured to decelerate and transmit driving force of the motor to the drive gear.
