Abstract
A rotation control apparatus includes an engagement lever configured to restrict a rotation of a pinion gear by engaging with a ratchet wheel and a drive lever driving and rotating the pinion gear in a direction where a seat moves upward by integrally rotating with an operation member in a state where the drive lever engages with the ratchet wheel based on a rotation operation of an operation handle in a first direction. The engagement lever disengages from the ratchet wheel by the rotation of the pinion gear in a case where the seat moves upward. The rotation control apparatus further includes an engagement lever control piece and a drive lever control piece which cause the engagement lever and the drive lever respectively to disengage from the ratchet wheel based on the rotation operation of the operation handle in a second direction.
