図）を有する。<Embodiment of the invention> Fig. 1 is a front view of a shield plate mounting structure according to the invention, Fig. 2 is a side view thereof, and Fig. 3 is a schematic perspective view. Two aluminum support members 2 are screwed onto a printed board 1, and heat generating components 3 such as power transistors and rectifier diodes are mounted on the support members 2.
a and 3b are attached. An aluminum shield plate 4 is fixed onto the flange 2a at the upper edge of the support member 2 with screws 5. In this example, the number of screws is 6.
The shield plate 4
The mounting hole is a round hole 6 (Fig. 4) with a diameter corresponding to the diameter of the screw 5, and the screw 5 is screwed into the screw hole 8 of the flange 2a of the support member 2 through this round hole 6, and the other 5 The mounting hole of the shield plate 4 is in the shape of a keyhole (FIG. 4), and the screw 5 is screwed into the threaded hole 8 of the flange 2a of the support member 2 through the keyhole 7. The keyhole 7 is a long hole as a whole, and has an enlarged hole 7a (fourth hole) through which the head of the screw 5 can pass through at one end.
