Abstract
A rotational angle detector has a rotary body, a first detecting unit rotating in cooperation with the rotary body, a second detecting unit rotating in cooperation with the first detecting unit, and an auxiliary detecting unit rotating in cooperation with the rotary body and the second detecting unit. The rotational angle detector has a first detecting element, a second detecting element, and a controller. The first detecting element detects rotation of the first detecting unit, and the second detecting element detects rotation of the second detecting unit. The controller detects a rotational angle of the rotary body based on a detection signal supplied from the first detecting element and a detection signal supplied from the second detecting element.
