Claims

[Scope of utility model registration request]

A heat dissipation structure in a power supply device comprising a circuit board on which a heat generating circuit component with a lead terminal led out from an element body is mounted on a chassis, the element body being mounted opposite to the circuit board, A notch provided in the circuit board corresponding to the element body, a positioning hole provided in the chassis corresponding to the notch, and a positioning hole provided in the element body corresponding to the positioning hole. and a fixing member that is commonly inserted into the positioning hole and the mounting hole to fix the element body and the chassis, and the element body and the chassis pass through the notch. 1. A heat dissipation structure for a power supply device, wherein the element main body is attached to the chassis by the fixing member so as to be rotatably adjustable.
