Japanese Patent JP2022185233

A

To provide an electronic apparatus which has a rotary operation member and is excellent in dust-proof drip-proof performance.SOLUTION: An electronic apparatus 100 comprises: a rotary operation member 200 which can rotate; a base member 240 which holds the rotary operation member in a rotatable manner; a magnet 210 which can be integrally rotated with the rotary operation member and in which the N pole and the S pole are alternately magnetized in a rotation direction; and a first magnetic body 220 and a second magnetic body 230 which are arranged on both sides across the magnet in an axial direction in which the rotation central axis of the rotary operation member extends, and have a plurality of comb teeth parts 221, 231 extending radially toward the outer side in the radial direction from the center part. In the axial direction, the first magnetic body, the magnet and the second magnetic body are arranged on the side opposite to the rotary operation member across the base member. In the rotary operation member, a portion of the outer peripheral part thereof is exposed to the outside from an opening 11 provided in an exterior member 10 of the electronic apparatus.
