Non-reciprocal circuit element, communication equipment using the same, and, assembling method of non-reciprocal circuit element

摘要

The present invention has excellent nonreciprocal circuit characteristics, and to provide a non-reciprocal circuit device which can reduce costs. In the non-reciprocal circuit device according to the invention, the magnetic rotor assembly 1 is housed in a retainer. Retainer, a case portion 3, and a lid 4. Side walls 31 to 33 of the case portion 3, the peripheral edge of the bottom surface 34, and rises to be spaced apart from each other, has a recess 36 on the end edge of the rising portion. Side walls 41 to 43 of the lid portion 4, from the periphery of the lid surface 34, falling spaced apart from each other, and has a protrusion 46 on the end edge of the trailing edge. The lid portion 4, the convex portion 46 is fitted in the recess 36, is combined with the case portion 3. In the fitting state, the end face 461 of the convex portion 46, mutually pressed against the inner surface 361 cusp P of the recess 36, , the end face 462 of the convex portion 46, a gap between the inner surface 362 of the recess 36 G is I have caused.
