A lever apparatus (50) includes a lever (60) operated by a user, a biasing member (97) that is a source of an operation reaction force of the lever (60), and a linkage mechanism (81) configured to link the lever (60) and the biasing member (97). The linkage mechanism (81) includes a lever-side rotating body (82) pivoted according to pivoting of the lever (60), and a biasing member-side rotating body (91) engaged with lever-side rotating body (82) and installed closer to the biasing member (97) than the lever-side rotating body (82). The linkage mechanism (81) varies a ratio (dθ2/dθ1) of a variation (dθ2) of a rotation angle of the biasing member-side rotating body (91) to a variation (dθ1) of a rotation angle of the lever-side rotating body (82) according to an operation amount of the lever (60).
