Abstract:
A rotational angle detector includes a rotary element rotatable around a rotational axis line, the rotary element having a detected portion on an outer circumference, a detection element provided on a radially outside of the detected portion so as to face the detected portion, and a seat having a mounting surface on which the detection element can be mounted, the mounting surface extending around the rotational axis line. The seat is configured such that a distance between the mounting surface and the detected portion in a direction parallel to the rotational axis line varies along a circumferential direction of the seat.
