Abstract: A power relay device is provided that relays power from a power source and supplies the power to an electric component. The power relay device includes a main device body, a terminal cover, and a holding unit. The main device body includes a power source terminal electrically connected to the power source and a load terminal electrically connected to the electric component. The terminal cover includes a connection terminal electrically connectable to a connected subject that is one of the power source terminal and the load terminal. The holding unit selectively sets a temporary holding state in which the connection terminal is electrically disconnected from the connected subject or a final holding state in which the connection terminal is electrically connected to the connected subject.

Abstract: The fixing member includes a lower contact member 32 and an upper contact member (contact members) that come in contact with a battery to support the battery between a driver seat and a passenger seat (vehicle seats), and the lower contact member and the upper contact member are deformed when a load of a predetermined value or more is input from a vehicle width direction, to allow movement of the battery in the vehicle width direction.
