Abstract
A reaction force generator includes: a base member mounted on a supporter supporting an operating member pivotably; a dome member protruding from the base member; and a top member provided on a protruding-side end of the dome member to be pressed by the operating member toward the base member. The dome member is deformed to produce a reaction force when the top member is pressed by the operating member. A basal-end-side plane and a distal-end-side plane 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. The basal-end-side plane includes a line of intersection between the base member and the dome member adjacent to each other. The distal-end-side plane includes a line of intersection between the dome member and the top member adjacent to each other.
