1. An electric vehicle structure, comprising:
- a floor frame member;
a floor panel on the floor frame member;
a battery frame including, an outer frame having side portions connected with the floor frame member on right and left sides and transverse portions connected with the side portions on front and rear sides, the outer frame partitioning a battery compartment; and
a flange extending from an inner peripheral portion of the outer frame and having an inclined flange wall extending toward the battery compartment;
a battery cover over the battery compartment having an inclined cover wall matingly engageable with the inclined flange wall;
a sealing member between the flange and the cover to provide waterproofing between the walls, and a fixing member connecting the cover to the flange.

Abstract
A flange is provided upright on a top inner peripheral portion of an outer frame of a battery frame. The flange is formed inward with a gradient. A peripheral side wall of a battery cover is formed outward with a gradient to mate with an inclined angle of the flange. The peripheral side wall is taper-fitted onto the outer side surface of the flange via a sealing member and then engaged therewith. Accordingly, since no outward extended element is provided in the flange, the interference between the flange and the floor frame member is avoided and thus battery installing operability is improved.
