To provide an inexpensive electrically-operated bed which can adjust a position of the rising position of a bed and so on to any positions easily, and use an electric actuator which is attached and detached easily.

The electrically-operated bed turns a bed by the electric actuator 10. of the electric actuator is set up on a part outside the framework of the electrically-operated bed. A drive member 12 is set up on the foot of a bed of the electrically-operated bed. The driving of a motor 13 is transmitted to the drive member 12 through a clutch 14, a torque limiting circuit as a vehicle and turns a bed. The motor base 11 and the drive member 12 can be attached and removed at will by a coupling 15 set up between the clutch 14 and the drive member 12.
