Abstract: A case includes a guide portion to guide sliding of a shutter to open and close a discharge port of a case body, a main pathway at which an end of the shutter is located when the shutter is in a state to open the discharge port, and first and second branching pathways into which the end of the shutter can be selectively inserted when the shutter is in a state to close the discharge port. When a pin is fitted into the case body, the end of the shutter is inserted into the first branching pathway, and when the pin is not fitted, the end is inserted into the second branching pathway, so that it is apparent from the exterior that the distal end is inserted into the first or second branching pathway.

Abstract: Conductors of first and second current sensor units are parallel or substantially parallel to each other with a space therebetween. An arch-shaped portion and an inverted arch-shaped portion of the first current sensor unit are at different positions from positions of an arch-shaped portion and an inverted arch-shaped portion of the second current sensor unit. When seen in a width direction, first and second magnetic sensor elements of the first current sensor unit are outside an opening of the second current sensor unit and first and second magnetic sensor elements of the second current sensor unit are outside an opening of the first current sensor unit.
