Abstract

Winding components, each being formed by winding a coil around and along an inner peripheral surface and an outer peripheral surface of a ring-shaped core a plurality of times, are fixed to a case. An attachment structure includes a placing member made of an insulating material and fixed to a fixing surface of the case in a state where a lower surface of the winding component is placed, a pressing member made of an insulating material and disposed to abut on an upper surface of the winding component, and a pressing force imparting portion that couples the placing member with the pressing member and imparts a pressing force toward the fixing surface, from the pressing member to the winding component, and in the pressing force imparting portion, a distance between the placing member and the pressing member is variable in accordance with a height change of the winding component.
