The purpose of the present invention is to provide a lens holder of an injector for an intraocular lens, wherein the lens holder is configured such that axial shifting of a plunger within the lens holder can be effectively prevented. A lens holder 4 of an injector 1 for an intraocular lens is provided with: a holder body 61 having a mount unit 62 on which an optical unit 91 of an intraocular lens 90 is placed, the holder body 61 having formed in the proximal-end side thereof an insertion hole 63 for a plunger 3 for pushing out the optical unit 91 positioned on the mount unit 62 toward the distal end of the holder body 61; and an axial-shift-preventing unit 110 provided within the holder body 61 between the mount unit 62 and the insertion hole 63 and in the movement path of the plunger 3, the axial-shift-preventing unit 110 being an elastic member that deforms in conformance with the shape of the plunger 3 when the plunger 3 moves toward the distal end.
