An electric bed includes a base support frame and an end frame pivotally connected with the base support frame, such that the end frame can be turned downwardly from a horizontal position and restored to the horizontal position by a position-restoring device. A driving member has two ends pivotally connected with the base support frame and a rotatable frame, respectively. The rotatable frame has a front end pivotally connected with a rear end of the base support frame and positioned above the end frame, and a pushing plate connected with the driving member directly or indirectly. Therefore, the driving member can drive the rotatable frame to press the end frame to turn downwardly from the horizontal position. The position-restoring device returns the end frame to the horizontal position while the end frame is not acted by the driving member.
