Zusammenfassung: | Disclosed in the present invention is a lightweight vehicle body frame for an electric car, which provides excellent structural strength, and can be easily manufactured. The vehicle body frame for an electric car according to an embodiment of the present invention comprises: a first side member and a second side member which are spaced apart to face each other, wherein each of the first side member and the second side member comprises a main beam unit of a straight shape, a first inclined beam unit which is extended from one end of the main beam unit while being upwardly bent, a first reinforcing beam unit which is extended from an end portion of the first inclined beam unit while being in parallel with the main beam unit, a second inclined beam unit which is extended from the other end of the main beam unit while being upwardly bent, and a second reinforcing beam unit which is extended from an end portion of the second inclined beam unit while being in parallel with the main beam unit; a first connecting member and a second connecting member which are spaced apart to face each other, wherein each of the first connecting member and the second connecting member is vertically provided between the main beam unit of the first side member and the main beam unit of the second side member; a front member of a C-shape, which is composed of a pair of rectilinear beam units which are spaced apart to face each other, and a connecting beam unit which connects an end portion of the pair of rectilinear beam units, and is coupled to the first connecting member; and a rear member of a C-shape, which is composed of a pair of rectilinear beam units which are spaced apart to face each other, and a connecting beam unit which connects an end portion of the pair of rectilinear beam units, and is coupled to the second connecting member.
