Abstract
The sensor magnets have, on a side facing the attraction plate: an S1 magnetized portion magnetized to an S pole; an N2 magnetized portion located at a position adjacent to the S1 magnetized portion in an L1 direction, and magnetized to an N pole; an S3 magnetized portion located at a position adjacent to the N2 magnetized portion in an L2 direction intersecting the L1 direction, and magnetized to the S pole; and an N4 magnetized portion located at a position adjacent to the S3 magnetized portion in an L3 direction intersecting the L2 direction and adjacent to the S1 magnetized portion, and magnetized to the N pole. The attraction plate overlaps at least part of the S1 magnetized portion, the N2 magnetized portion, the S3 magnetized portion, and the N4 magnetized portion, when viewed in an optical axis direction.
