る貫通ブツシング構造。[Claims for Utility Model Registration] A bushing formed by a cylindrical portion and a flange portion formed concentrically and integrally at approximately the midpoint in the longitudinal direction of the cylindrical portion, through which a conductor is inserted into the cylindrical portion. In a through-butting structure in which the flange part is joined to the metal plate by inserting one end of the cylindrical part into a through hole formed in a metal plate and integrally molding the flange part with the short cylindrical part and the end of the short cylindrical part. A mounting portion of a withstand voltage drop prevention member made of a conductive material is sandwiched between the metal plate and the flange portion, and a mounting portion of the short cylindrical portion is mounted. A through bushing structure characterized in that the relationship between the radius R 1 of the radius of the inner peripheral end on the side and the radius R 2 of the radius of the inner peripheral end on the side opposite to the attachment part satisfies R 1 ≧ R 2 .
