Electric connector attachment structure of battery pack for electric vehicle

To provide an electric-connector attachment structure of a battery pack for an electric vehicle, which can attach an electric connector to a battery pack even when the height of the battery pack for an electric-vehicle is set low, the electric-connector attachment structure includes: a battery pack 3 for an electric vehicle including a tray 4 of a box-like shape which accommodates a battery and has an opening on an upper side, and a cover 5 of a box-like shape having an opening on a lower side, the tray 4 and the cover 5 being joined at a horizontal plane; and an electric connector 6 to which an electrical cable 61 is connected. It further includes an inclined portion 441, 551 to which the electric connector 6 is connected, disposed at an inner side of the battery pack 3 with respect to a joint surface 461 at which the tray 4 and the cover 5 are joined, extending over lower and upper regions across the horizontal plane H passing through the joint surface 461; and a protruding portion 443, 553 disposed between the joint surface 461 and the inclined portion 441, 551 so as to protrude from the horizontal plane passing through the joint surface 461 in a direction opposite to the electric connector 6. The inclined portion 441, 551 is formed so as to be continuous from the protruding portion 443, 553.
