COMPONENT MOUNTING STRUCTURE AND PUSH NUT

Manufacturing costs are reduced. Connection strength and easiness for mounting are improved. A component mounting structure comprises a fastener includes a first fastener (41) and a second fastener (61), wherein the second fastener is pressed into the first fastener to pinch a component between the first fastener and the second fastener. The fastener further includes a push nut (31) into which an end portion of the first fastener is inserted. The push nut includes a base plate (32) that has an annular shape, a first engaging portion (33) formed inside the base plate and inclined relative to the base plate in a direction towards a bottom portion of the recess and a second engaging portion (34) formed outside the base plate and inclined relative to the base plate in a direction opposite to the direction towards the bottom portion of the recess.
