Summary:PURPOSE:To accurately detect the rotation angle of an oscillation type yoke by providing an energizing means eliminating play among the yoke, a shaft member, and a rotation angle detector with first and second joining means. CONSTITUTION:In a shaft 22, an axis part 36, positioned on the upper part opening side of a pivot 14, is supported swingingly in three dimensions with a spherical bearing 24. A first joining means is composed in which the rotation of a yoke is transferred to the shaft 22 with a degree of slidable freedom in fore and aft, left and right, and up and down by linking the lower end of the shaft 22 and the control arm 138 side. Moreover the linking structure of the shaft 22 and a detection joint 36 on a potentiometer 20 side composes a second joining means in which rotation from the yoke received via the shaft 22 is transferred to the potentiometer 20 with a degree of slidable freedom in fore and aft, left and right, and up and down. Moreover a play-eliminating spring 60 is provided on the outside of the joint 36 fixed to the input axis 34 of the potentiometer 20. Thus the rotation angle of an oscillation type yoke can be correctly detected.
