Abstract
A rotation-angle-detection device includes a main housing, a resinous cover for covering an opening of the main housing, a permanent magnet disposed at the main housing to be rotatable in response to rotation of a throttle valve, and a magnetic sensor. The cover is longer in longitudinal direction than in lateral direction, and the magnetic sensor is fixed to the resinous cover. The magnetic sensor is disposed so that the detection direction and the longitudinal direction of the cover cross each other at a right angle.
