摘要： TASK
To allow the rotational position of the seat cushion of a vehicle seat device to be manually adjusted by the occupant of the seat device.
MEANS
The vehicle seat device has a rotation device provided between a floor and a seat cushion to rotatably support the seat cushion relative to the floor. The rotation device comprises a base portion provided on the floor; a rotatable portion provided on the seat cushion and rotatably supported by the base portion; an electric actuator 53 for rotating the rotatable portion with respect to the base portion; and a rotation lock device 54 for selectively prohibiting rotation of the rotatable portion with respect to the base portion. The rotation lock device is configured to be manually switched between a locked state and a released state. The electric actuator is configured to allow rotation of the rotatable portion with respect to the base portion when the rotation lock device is released and electric power is not supplied to the electric actuator.
