A rotational angle detection device includes: a main driving gear; two driven gears; two sensors that detect the respective rotational angles of the two driven gears; and a computation circuit configured to compute the rotational angle of the main driving gear based on the respective rotational angles of the two driven gears. The computation circuit includes a difference computation circuit and a wear detection circuit. The difference computation circuit is configured to compute a first difference. The wear detection circuit is configured to detect wear of the two driven gears through a comparison between a value of the first difference that is computed by the difference computation circuit and a first ideal value.
