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.本發明提供一種於眼內水晶體注射器之水晶體架中能夠有效地防止水晶體架內部之柱塞之軸抖動之構成。眼內水晶體注射器1之水晶體架4具備：架本體61，其具有設置眼內水晶體90之光學部91的載置部62，且於基端側形成將設置於載置部62之光學部91擠出至前端側之柱塞3的插入口63；及作為彈性構件之軸抖動防止部110，其設置於架本體61之內部中之載置部62與插入口63之間且柱塞3之移動路徑，若柱塞3移動至前端側，則跟隨該柱塞3之形狀而變形。
