Claim:
1. A winding component attachment structure in which a winding component is fixed to a case, the winding component 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, the attachment structure comprising: 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, wherein 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, and a part of the lower surface of the winding component is placed on the placing member, and the winding component is pressed and fixed to a side of the fixing surface in a state where a cushioning material that absorbs a vibration transmitted to the case is sandwiched between the residual part of the lower surface of the winding component and the fixing surface.
