検出装置。[Claims for Utility Model Registration] (1) As a means for detecting the rotation angle of one member rotating around the connecting shaft of two members as a fulcrum, the connecting shaft is divided into a first shaft and a second shaft. the first shaft is fixed to one member that rotates, the second shaft is fixed to the other member that does not rotate, and the first shaft and the second shaft are opposed to each other. A rotation angle detection device characterized by having a potentiometer built into the space created by the end face. (2) A first shaft 1 which is fixed to one rotating member 5 and has a flanged bushing 3 and a spline bushing 2 having a spline on the inner periphery press-fitted into a recess at the shaft end; The small diameter part of the tip is inserted into the flanged bushing 3, and the large diameter part is fixed to the other member. 2. The rotation angle detection device according to claim 1, further comprising a built-in potentiometer 10 mounted on the end face of the second shaft 8, with a pinion 12 fitted and slidable fixed to the shaft end.
