A means (screw 33c and spring 34c) for adjusting the azimuth of the second head 1 at the tip of this projecting piece 3c
has been established. Therefore, it is possible to perform fine adjustment of the azimuth and electrical phase adjustment while maintaining a sufficiently large distance from the means for adjusting the azimuth of the second head 1 to the supporting position of the second head 1. Moreover, by effectively utilizing the width of the first head, the overall structure can be made compact. Further, the azimuth adjustment of the second head can be easily performed by using the azimuth adjustment screw 33c located at the tip of the protrusion after the head device is assembled.
