Abstract
A relative angle sensing device that senses a relative rotation angle between first and second rotary shafts includes: 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. A transmitting unit is provided between the rotary component and the supported component. The transmitting unit transmits rotative force of the one rotary shaft to the supported component by direct contact with each other in a case of peeling of the adhesive material.
