Abstract
An electric power device for a vehicle has a case that is divided into a first case and a second case. The first case and second case are coupled so as to be separable from each other by the shock of a crash. In the power device, furthermore, a part of the first case and the second case, or a coupling member coupling the first case to the second case, is laminated, and a shock breakage pin to be broken by a predetermined shock penetrates through a laminated portion to couple the first case to the second case.
