Abstract:
1. A holding structure of an intervening member, comprising: a first member; a second member provided parallel to the first member; the intervening member provided between the first member and the second member, and having a supporting plate portion facing the first member or the second member, the supporting plate portion having a through-bore with an axis center extending in a direction perpendicular to the first and second members; and an elastically deformable wobbling-prevention member provided between the intervening member and at least one of the first and second members in a compressed state to prevent the intervening member from wobbling; wherein the wobbling-prevention member integrally includes: an axis portion slidably passing through the through-bore of the supporting plate portion, and having one end portion positioned on a side of the first member relative to the supporting plate portion, and another end portion positioned on a side away from the first member relative to the supporting plate portion, the axis portion being slidably displaceably fitted in the through-bore of the supporting plate portion; an elastic head portion integrally provided on the one end portion of the axis portion, with a radius thereof expanding from the one end portion to the supporting plate portion and a height thereof reducing from a center toward an outer peripheral edge portion thereof, the center thereof being highest so that when an external force is received, the center of the elastic head portion abuts against the first member, and the outer peripheral edge portion of the elastic head portion abuts against the supporting plate portion to prevent the intervening member from wobbling; and a bulging portion formed on the side of the another end portion of the axis portion relative to the supporting plate portion and having a radius thereof expanding more than a radius of the through-bore, said bulging portion being elastic to pass through the through-bore and clamping the supporting plate portion in cooperation with the elastic head portion, the axis portion is positioned in a loosely fitted state relative to the through-bore to form an annular gap between the axis portion and an inner peripheral surface of the through-bore; and an internal space inside the elastic head portion faces an outside through the annular gap, the intervening member further comprises a concave portion having a bottom portion as the supporting plate portion arranged with the through-bore, and a sidewall portion defining an inner peripheral edge of the concave portion, and the elastic head portion of the wobbling prevention member protrudes outside of an opening of the concave portion beyond the sidewall portion of the concave portion from the inside of the concave portion to abut the first member, and the intervening member further comprises a control wall portion extending perpendicular to the supporting plate portion; and the supporting plate portion comprises a connection wall portion extending parallel to the first member to face the first member and connected to the control wall portion, and a supporting portion protruding toward the first member, the supporting portion having the concave portion with the through-bore.
