Abstract

A rotary input device includes a first annular magnetic body (11) in which a plurality of outward protrusions (11a) protruding toward an outside in a radial direction are disposed along a circumferential direction, a second annular magnetic body (21) in which a plurality of inward protrusions (21a) formed to oppose the outward protrusions (11a) of the first magnetic body (11) are disposed along a circumferential direction, and a rotary knob (20) configured to relatively rotate the first magnetic body (11) and the second magnetic body (21). The first magnetic body (11) includes a magnet (12) in which opposing surfaces (12a, 12b) facing each other are vertically disposed and which is magnetized to two poles of an upper pole and a lower pole including the opposing surfaces (12a, 12b), a pair of yokes (13, 14) that interposes the opposing surfaces (12a, 12b) of the magnet (12) vertically, and the outward protrusion (11a (13a), 11a(14a)) formed on the pair of yokes (13, 14).
