| description | A rotatable operation apparatus includes a rotatable operation member, a magnet having alternately magnetized magnetic poles, first and second magnetic members respectively including first and second teeth, a body frame, and a detector. A magnetized direction of each magnetic pole is parallel to a predetermined axis about which the rotatable operation member rotates. The magnet has a ring shape and is configured to rotate about the predetermined axis as the rotatable operation member rotates. The rotatable operation apparatus generates an operation force according to a change in positions of the magnetic poles, caused by the rotation of the magnet, relative to positions of the first tooth and the second tooth. The magnet, the first magnetic member, and the second magnetic member are housed inside the body frame. When viewed from a thrust direction of the magnet, the detector is disposed at a position that does not overlap with the magnet. |
