POWER SWIVEL DEVICE OF SEAT FOR VEHICLE

The present disclosure relates to a power swivel device for a vehicle seat where a brake unit is installed between a fixed plate mounted to a seat rail and a rotating plate mounted to a seat. The brake unit delivers rotational force of the motor to the rotating plate when the motor is operated and constrains a flow in a rotational direction of the rotating plate when the motor is stopped. Accordingly, it is possible to prevent a flow of a seat in a rotational direction due to gear backlash.
