A base of a foldable baby bed has two axles each trunally passed through a pair of receiving holes of a main body. The axles are each pivoted to two connecting rods form two ends: the connecting rods are pivoted to the frame of the bed. The main body has a controlling handle with two end cam parts being fitted onto hollows on two sides of the main body. A pivotal bolt is passed through the cam parts through hole on the hollows, connected to a connecting bolt up-and down movably passed through a receiving room on a top portion of the main body. The through holes have elongated opening for the pivotal bolt, and the connecting bolt to move up and down by pivoting the handle on the pivotal bolt. The connecting bolt is connected to an engaging board movably received in the main body. The engaging board has engaging holes on two end portions for separably engaging rod-shaped engaging parts sticking out from the middle of the corresponding axles. Thus, the engaging board can be easily moved up to lock the axles to fix the connecting rods in a stretched position with the controlling handle, and moved down for the axles to turn in order to fold the baby bed.
