Abstract:
1. A relative angle sensing device that senses a relative rotation angle between a first rotary shaft and a second rotary shaft, the relative angle sensing device comprising: a rotary component that is provided on one rotary shaft out of the first rotary shaft and the second rotary shaft, and that rotates together with the one rotary shaft; a supported component that generates a magnetic field and that is supported by the rotary component through an adhesive material; and a sensor that is provided in the other rotary shaft out of the first rotary shaft and the second rotary shaft, and that outputs a value corresponding to the magnetic field generated by the supported component, wherein a convex part is provided in any one of the rotary component and the supported component and a concave part is provided in the other one of the rotary component and the supported component, and the supported component is supported by the rotary component through the adhesive material in a state where the convex part and the concave part are fitted with each other, and the rotative force of the one rotary shaft is transmitted by direct contact between the convex part and the concave part in the case of peeling of the adhesive material.
