Abstract
In order to ensure waterproofing between a resin enclosure case and a heat sink, a canopy structure is provided in a portion, in which water is likely to penetrate, so as to prevent the water from entering the portion, thereby directing the water flow to the outside of the enclosure. This makes it easy to install and remove an electronic unit, so that an electronic component integrally formed with the heat sink can be easily replaced.
