<p>The present invention relates to a heat radiating device for a brush holder assembly for a start motor, wherein the heat radiating device includes: an insulating plate being formed with insulating material, being installed inside a rear bracket formed with metal material, and having a brush connected to a brush wire; a backup plate being installed between the rear bracket and the insulating plate, being formed with metal material connected to the rear bracket, and increasing a heat radiation area with being connected to the brush wire. In contrast with an existing technology, the present invention is capable of maximally radiating heat, which is generated in the brush wire, in a short time by increasing the heat radiation area at the rear bracket, thereby improving heat radiation efficiency.</p> |
