るヒートシンクの固定構造。[Claims for Utility Model Registration] Fixing of a heat sink that fixes a heat sink made of a metal plate with good thermal conductivity that radiates heat generated by the semiconductor element to which a semiconductor element is attached almost perpendicularly to a printed circuit board. The heat sink has a structure in which the heat sink protrudes from one side, is bent along one main surface of the printed circuit board at a nearly right angle halfway, and has a screw hole in the locking part between the bent part and the tip part. and a screw-fastening piece that protrudes from the above-mentioned side of the heat sink in the same direction as the screw-fastening piece, is fitted into a notch or hole formed in the printed circuit board, and is bent toward the other main surface side of the printed circuit board. a locking piece that is fixed to the printed circuit board with a locking piece, and a contact piece that protrudes from the one side of the heat sink in the same direction as the screw fixing piece, and whose tip surface abuts the one main surface of the printed circuit board,
A fixing structure for a heat sink, characterized in that the screw fixing piece is screwed to the printed circuit board with the printed circuit board sandwiched between the tip surface of the contact piece and the locking part of the locking piece.
