The present invention is provided with: an approximately cylindrical nozzle body a stage part which is provided in the nozzle body and houses an intraocular lens a plunger which presses the intraocular lens housed in the stage part by the forward end thereof to discharge the intraocular lens into an eyeball and a positioning member which restricts the initial position and posture of the intraocular lens by being mounted to the stage part from the outside. Rib sections are formed so as to extend in the front-back direction of the nozzle body at the outer periphery of the stage part, and side wall parts and rotation prevention wall parts are formed in the positioning member so as to sandwich the rib sections from both sides, thereby restricting the rotation of the positioning member with respect to the stage part.
