Abstract
An assembly structure of a sensor includes: a shaft; a housing including: a first cylindrical part; and a first annular plate that is an annular plate, an outer periphery of which is connected to an end of the first cylindrical part, and that is orthogonal to a rotation axis of the shaft; a magnet accommodated inside the first cylindrical part in a radial direction and fixed to an end of the shaft; a sensor configured to detect rotation of the magnet; and a holder that is fixed to the first annular plate and that holds the sensor such that the sensor is disposed at a predetermined position with respect to the magnet.
