A reaction force generator (5; 9; 12; 19) includes: a base member (6) mounted directly or indirectly on a supporter (2) supporting an operating member (4) pivotably; a dome member (7; 10; 13) protruding from the base member; and a top member (8; 11; 20) provided on a protruding-side distal end of the dome member and configured to be pressed by the operating member toward the base member. The dome member is configured to be elastically deformed to produce a reaction force when the top member is pressed by the operating member. The dome member is configured such that a basal-end-side plane (BP) and a distal-end-side plane (TP) intersect each other at a position located on one of opposite sides of the dome member which is nearer to a pivot fulcrum of the operating member than another of the opposite sides. The basal-end-side plane includes a line (BL) of intersection between the base member and the dome member adjacent to each other. The distal-end-side plane includes a line (TL) of intersection between the dome member and the top member adjacent to each other. |
