The purpose of the present invention is to provide an intraocular lens injector with which the tip side of a plunger can be finely formed while ensuring rigidity, and with which the occurrence of shaft deviation during contact with an intraocular lens can be effectively inhibited. A plunger (3) of this intraocular lens injector (1) is provided with: a tip-side shaft part (35) provided with an L-shaped section (36)； a central shaft part (33) which is formed flat, and which is wider than the tip-side shaft part (35)； and a part (40) to be restricted which is formed from the tip-side shaft part (35) to the central shaft part (33), and which protrudes from the flat surface at the central shaft part (33). Furthermore, an opening (70) in a main body (2) is provided with: a central opening (71) which is open in accordance with the shape of the central shaft part (33)； and a restriction part (72) formed so as to protrude from the end surface of the central opening (71), in the thickness direction of the central shaft part (33), in accordance with the shape of the part (40) to be restricted. The part (40) to be restricted has a length in the axial direction which is set such that the part (40) to be restricted is restricted by the restriction part (72) in an interval from an initial position before the L-shaped section (36) begins to be in contact with a second lens support part (93) of an intraocular lens (90), to a position in which the L-shaped section (36) is in contact with the second lens support part (93).本發明提供一種眼內透鏡用注射器，其能夠於確保剛性之同時且使柱塞之前端側形成得較細，並且能夠有效果地防止與眼內透鏡接觸時之軸向偏轉之發生。眼內透鏡用注射器1之柱塞3包括：前端側軸部35，其具有L字部36；中軸部33，其形成為較前端側軸部35寬幅之扁平狀；以及被限制部40，其自前端側軸部35形成至中軸部33且於中軸部33自扁平面突出。而且，本體2之開口部70包括：中央開口部71，其相應於中軸部33之形狀而開口；以及限制部72，其相應於被限制部40之形狀，以自中央開口部71之端面向中軸部33之厚度方向突出之方式形成。被限制部40以於自L字部36開始與眼內透鏡90之第2透鏡支持部93接觸前之初始位置至接觸為止之期間內由限制部72限制的方式，設定其軸方向之長度。
