とするパワートランジスタの取付構造。 A power transistor was attached via an insulating sheet to the side surface perpendicular to the printed circuit board of a heat dissipation fin fixed to a printed circuit board, and this power transistor was mounted on the printed circuit board by pressing it against the heat dissipation fin with a holding metal fitting. In the device, the presser metal fitting is provided with a fixed leg for fixing it to the printed circuit board, and a presser tongue piece that presses the center of the molded portion of the power transistor toward the heat dissipation fin, and the fixed leg is arranged in a longitudinal direction. A supporting piece is bent at a right angle to the molded part of the power transistor, and a supporting piece is formed in a direction perpendicular to the molded part of the power transistor. A power transistor mounting structure characterized by having a protrusion.
