PROBLEM TO BE SOLVED: To normally energize a bed body in a closing direction by a closing direction drive mechanism while reducing a space around a rotary shaft.SOLUTION: A folding bed comprise: a base; a bed body rotatably arranged in the base via a rotation part so as to be in an open state and a closed state; a leg pipe rotatably arranged on the lower surface of the bed body and to be rotated between the open position and the closed position in accordance with the rotation of the bed body; and a closing direction drive mechanism arranged in the rotation part so as to rotate the bed body in a closing direction. The closing direction drive mechanism comprises: a driven link whose one end is rotated around a rotary shaft of the rotation part so as to transmit rotation force in the closing direction to the bed body; a drive link whose one end is rotatably attached to the base; a closing direction drive spring connected between the other end of the drive link and the base; and a transmission link for connecting the other end of the driven link to the actuation point of the drive link. |
