Abstract
An absolute encoder includes a first drive gear (worm gear 1d) configured to rotate in accordance with rotation of a main spindle, and a first driven gear (worm wheel 2a) that engages with the first drive gear. The absolute encoder includes a second drive gear (worm gear 2b) provided coaxially with the first driven gear and configured to rotate in accordance with rotation of the first driven gear, and a second driven gear provided, in a plan view, on a side opposite the first drive gear with respect to the first driven gear and the second drive gear, the second driven gear engaging with the second drive gear. The absolute encoder includes an angular sensor configured to detect a rotation angle of a rotating body that is rotated in accordance with rotation of the second driven gear.
