1. A follower bearing comprising:
an inner member including a first body and a flange, the first body having a rod shape and having an annular first rolling surface in an outer peripheral surface of the first body, the flange having an annular shape, disposed on the outer peripheral surface at one end of the first body, having a center axis coaxial with the first body, and having a diameter larger than a diameter of the first body;
an outer ring having, in an inner peripheral surface, an annular first surface, an annular second rolling surface, and an annular second surface, the first surface facing an outer peripheral surface of the flange, the second rolling surface facing the first rolling surface and the second rolling surface having a diameter smaller than a diameter of the first rolling surface, the second surface connecting the second rolling surface and the first surface to each other;
a plurality of rolling elements disposed to be rollable on the first rolling surface and the second rolling surface; and
a first sealing member including an annular first portion and an annular second portion, the first portion being disposed between the outer peripheral surface of the flange and the first surface and at least partially forming a sealing structure between the first portion and the outer ring, the second portion being connected to the first portion,
wherein the flange includes a first end surface and a second end surface, the first end surface being at an end of the flange opposite to the first rolling surface in an axial direction, the second end surface being at an end of the flange opposite to the first end surface in the axial direction,
the second surface being opposite to the second end surface in the axial direction,
the second portion being disposed between the second end surface and the second surface and projecting inward in a radial direction,
the first portion having an outer diameter that increases toward the first end surface in the axial direction, in a region extending from a connecting portion with the second portion to a first sealing end surface located near the first end surface in the axial direction.
