角検出装置。 A second member is rotatably attached to the first member via a coupling pin, an angle sensor is fixedly provided on the first member, and the relative swing angle of the second member with respect to the first member is measured via a lever mechanism. A bolt hole is drilled in the lever end on the second member side that is to be detected, and a lever end receiving metal fitting is provided on the boss fixed to the second member so as to be able to rotate freely around the axis of the boss. When connecting the lever end to the boss of the second member by forming a guide surface that corresponds to the longitudinal side surface of the lever end on the end receiving metal fitting, and drilling a bolt hole in the axis of the lever end receiving metal fitting. The longitudinal side surface of the lever end is adapted to the guide surface of the lever end receiving metal fitting, and the lever end and the lever end receiving metal fitting are each passed through a bolt hole and bolted to the boss. Swing angle detection device.
