Abstract: A click mechanism includes a first magnetic body having a first protrusion, a second magnetic body having a second protrusion, and a magnet configured to magnetize at least one of the first magnetic body and the second magnetic body. The click mechanism is configured to, in accordance with input operation, move at least one of the first magnetic body and the second magnetic body relative to the other, and generate click sensation corresponding to the input operation using magnetic attractive force generated between the first protrusion and the second protrusion. The second magnetic body further has a third protrusion configured to generate magnetic attractive force between itself and the first protrusion and differing in shape from the second protrusion.
