Car power source apparatus

A car power source apparatus comprising:

• a battery block having a plurality of connected batteries;
• a battery state detection section connected to the battery block;
• a base-plate that has the battery state detection section and the battery block mounted on a top thereof;
• a cover-plate that closes-off the top of the base-plate, establishes a battery holding region that holds the battery block between the base-plate and the cover-plate, and establishes an electronic component compartment that houses the battery state detection section between the base-plate and the cover-plate;
• and
• side-plates that close-off open regions between the cover-plate and base-plate at opposite ends,
• wherein the cover-plate is provided with a top cover that establishes the battery holding region inside, and an electronic component cover that establishes the electronic component compartment inside;
• wherein the base-plate and the cover-plate are overlapped in a layered manner at opposite sides thereof in a lateral direction to provide connecting regions;
• and
• wherein the car power source apparatus further comprises gaskets disposed in the connecting regions, respectively, the gaskets having projections that extend in a lengthwise direction, and the projections of the gaskets are sandwiched between the base-plate and the cover-plate at the connecting regions to make water-tight connections.
