A guide plate having a guide protrusion having elasticity in the groove width direction of the guide groove is fixed, and a cam ring is supported on this fixed cylinder so as to be movable in the optical axis direction as it rotates. A lens guide ring is supported so as to move integrally in the optical axis direction, and cam grooves and lens guide grooves for at least two moving lens groups, front and rear, are provided in the lens guide ring and the cam ring, respectively. The second group of movable lenses is provided with a guide pin inserted across both the cam groove and the lens guide groove, and the cam groove and the lens guide groove control the movement of the cam ring and the lens guide ring in the optical axis direction and the relative movement of the cam ring and the lens guide ring. A zoom lens barrel characterized in that the lens barrel is shaped so that the front and rear movable lenses are moved along a predetermined trajectory by a combined motion of rotation. (2) The zoom lens barrel according to claim 1, wherein the guide groove is a linear guide groove.
