摘要:
A waterproof box-like casing including, a box-like body having an opening, a lid for closing the opening and having a communication hole, and a bulkhead member for covering the communication hole hermetically. The communication hole provides communication between the inside and outside of the box-like body. Furthermore, the bulkhead member expands volume when the air inside of the waterproof box-like casing expands because of thermal expansion and contracts volume when the air inside of the waterproof box-like casing contracts because of thermal contraction.
