ABSTRACT:
According to the present invention, a hollowed portion is formed on a lower bonded surface of a rotary drum to which a rotation-side rotary transformer is bonded, and a hollowed portion is formed on an upper bonded surface of the fixed drum to which a fixation-side rotary transformer is bonded. Thus, excessive adhesive is absorbed by the hollowed portions and adhesive layers do not have uneven thicknesses, thereby securing surface runout accuracies of the rotary transformers. Further, since an adhesive is applied to the outer peripheral side of the hollowed portion of the rotary drum, the adhesive does not flow into ball bearings located on the inner peripheral side.
