1. An intraocular lens injector for injecting an intraocular lens into an eye, the intraocular lens including an optical portion having an optical function and support portions extending from the optical portion, the intraocular lens injector comprising:
a hollow body including an inner wall and a lens setting portion and defining a lens advancing direction;
a protrusion for bending a forward support portion while abutting against the forward support portion, the forward support portion being one of the support portions and being disposed forward of the intraocular lens in the lens advancing direction, when the intraocular lens advances along the inner wall of the hollow body in which the intraocular lens is set and thereby releasing the intraocular lens from the hollow body in a state in which the intraocular lens is folded with an inner surface of the optical portion facing inward,
wherein the protrusion comprises
an inclined surface that extends upwardly and in the lens advancing direction, defines a first slope, and is located at a rearmost side of the protrusion,
a step that includes a rising portion, which extends upwardly and in the lens advancing direction and defines a second slope that is greater than the first slope, a flat top portion, and a chamfered part between the rising portion and the flat top portion, and
an upwardly extending wall that is located forward of the flat top portion of the step.
