主权项

1. An electric storage apparatus comprising:
at least one electric storage device; a first external housing for holding the at least one electric storage device, the first external housing including a first vertical wall portion for surrounding an outer periphery of the at least one electric storage device; and a second external housing for housing the first external housing, the second external housing including a second vertical wall portion for surrounding the first vertical wall portion and an open portion formed at an upper end of the second vertical wall portion for inserting the first external housing therein, wherein the first vertical wall portion includes a flat outer surface, wherein the second vertical wall portion includes a flat inner surface, wherein the flat outer surface includes an inclined surface that is inclined so as to be more spaced apart from the second vertical wall portion toward a deeper side in an insertion direction of the first external housing, wherein one of the flat outer surface and the flat inner surface includes a protrusion portion that protrudes toward another one of the flat outer surface and the flat inner surface, and wherein the protrusion portion comprises a protruding ridge that is formed along the insertion direction of the first external housing so as to become thicker toward the deeper side in the insertion direction, and the protrusion portion abuts, over an entire length of the protrusion portion, against said another one of the flat outer surface and the flat inner surface.
