A lever apparatus includes a lever operated by a user, a biasing member that is a source of an operation reaction force of the lever, and a linkage mechanism configured to link the lever and the biasing member. The linkage mechanism includes a lever-side rotating body pivoted according to pivoting of the lever, and a biasing member-side rotating body engaged with lever-side rotating body and installed closer to the biasing member than the lever-side rotating body. The linkage mechanism varies a ratio of a variation of a rotation angle of the biasing member-side rotating body to a variation of a rotation angle of the lever-side rotating body according to an operation amount of the lever.
