PURPOSE: An electric powered bed for medical treatment is provided to obtain stability by maintaining angle between a mattress support plate and a lower body plate within standard range. CONSTITUTION: An electric powered bed for medical treatment (10) comprises a first hinge(320), a second hinge(420), and angle limiting parts(510,520). One end of the first hinge is gradually moving from the center of a main frame to a location where a back support is located as the back mattress supporting plate rises. One other end of the second hinge is gradually moving from the center to a location where a calf mattress supporting plate is located when a thigh mattress supporting plate rises. The angle limiting part diversifies one or more drives between the first and second motors when the angleγis 90 degrees or less so that the angleγcan be maintained as 90 degrees.
