ABSTRACT:
A rotation angle detection device includes a housing including a magnetic sensor, a rotation member rotatable relative to the housing and including a magnet facing the magnetic sensor, and a shaft member operated so as to rotate with an operated member. A rotation angle of the operated member is detected on the basis of a change of an output signal from the magnetic sensor rotatable relative to the magnet. The rotation member and the shaft member are connected to each other in such a manner that axes thereof are tiltable towards each other. Further, the rotation angle detection device includes a centering mechanism for retaining the rotation member and the housing member in a coaxial manner regardless of a tilting of the shaft member.
