A zoom lens barrel includes a fixed barrel, a guide barrel received in the fixed barrel, a cam barrel received in the fixed barrel and housing the guide barrel, a zoom barrel sandwiched between the guide barrel and the cam barrel, and a lens cover covering on the zoom barrel. The cam barrel includes a flange radially formed on an end close to the lens cover. The zoom barrel includes a ring portion protruding out from an end close to the fixed barrel. A step surface is formed between the outer side surface of the zoom barrel and that of the ring portion. When the zoom lens barrel is in an unfolded state, the step surface interferingly resists against a bottom surface of the flange, to limit an axial movement between the cam barrel and the zoom barrel.
