An inner frame includes a side wall being set its outer diameter to be smaller than a diameter of an inner periphery of a case and arranged along an inner peripheral surface of the case when the frame is housed within the case. The wall is divided into spread portions by cut outs, each cut out in a thickness direction of the case, and the spread portions are spread to make an outside surface thereof fit on the inner peripheral surface of the case when the module is press-fitted from an opening of the case. An inside surface of each spread portion is provided with a projection to be brought into contact with an outside surface of the module and to push and spread outward the spread portion when the module is press-fitted into the frame. A case unit includes the module, the case, and the frame.
