1. A battery pack frame for accommodating a plurality of secondary cells arranged in parallel with each other, each secondary cell extending axially in a first direction, the battery pack frame comprising: an upper frame for coupling with an upper portion of each of the plurality of secondary cells
1. A battery pack frame for accommodating a plurality of secondary cells arranged in parallel with each other, each secondary cell extending axially in a first direction, the battery pack frame comprising: an upper frame for coupling with an upper portion of each of the plurality of secondary cells so as to accommodate the plurality of secondary cells;a lower frame facing the upper frame, the lower frame being for coupling with a lower portion of each of the plurality of secondary cells, the upper and lower frames being spaced from each other in the first direction, wherein the upper frame has an inner side, the lower frame has an inner side, and the inner side of the upper frame faces the inner side of the lower frame; anda plurality of elastic members disposed in parallel with each other, extending between the inner side of the upper frame and the inner side of the lower frame in the first direction, and being in a space between areas for accommodating adjacent ones of the plurality of secondary cells,wherein the upper frame and the lower frame include fixing portions in which the plurality of secondary cells are insertable. 2. The battery pack frame as claimed in claim 1, wherein the fixing portions of the upper frame face the fixing portions of the lower frame. 3. The battery pack frame as claimed in claim 1, wherein the fixing portions of the upper frame and the fixing portions of the lower frame respectively include insert holes therein, the insert holes having a groove shape. 4. The battery pack frame as claimed in claim 1, wherein the fixing portions of the upper frame and the fixing portions of the lower frame respectively include insert holes thereon, the insert holes having a projectional shape. 5. The battery pack frame as claimed in claim 4, wherein the insert holes having the projectional shape include a projection wall extending inwardly in the first direction from the upper and lower frames. 6. The battery pack frame as claimed in claim 1, wherein the fixing portions include ventilating holes for establishing a fluidic connection between external air and upper end surfaces of the plurality of secondary cells. 7. The battery pack frame as claimed in claim 1, wherein: one end of each elastic member is fixed to the upper frame, andanother end of each elastic member is fixed to the lower frame. 8. The battery pack frame as claimed in claim 1, wherein the plurality of elastic members are alternately arranged with respect to spaces for accommodating the plurality of secondary cells. 9. The battery pack frame as claimed in claim 1, wherein the elastic members include an insulating material. 10. The battery pack frame as claimed in claim 1, further comprising a plurality of spacers between the upper frame and the lower frame, the spacers being parallel with the first direction. 11. The battery pack frame as claimed in claim 10, wherein: one end of each of the plurality of spacers is fixed to the upper frame or the lower frame, andanother end of each of the plurality of spacers is not fixed to the battery pack frame. 12. The battery pack frame as claimed in claim 10, wherein the plurality of elastic members and the plurality of spacers are alternately disposed to provide spaces therebetween for accommodating the plurality of secondary cells. 13. The battery pack frame as claimed in claim 10, wherein each spacer is surrounded by one of the elastic members. 14. The battery pack frame as claimed in claim 10, wherein each of the spacers includes one or more air ventilation holes. 15. The battery pack frame as claimed in claim 14, wherein the air ventilation holes have a rounded shape. 16. The battery pack frame as claimed in claim 14, wherein the air ventilation holes have a slit shape. 17. The battery pack frame as claimed in claim 10, wherein: ends of some of the spacers are fixed to the upper frame,ends of other spacers are fixed to the lower frame, andthe spacers having ends fixed to the upper frame are alternately disposed relative to the other spacers having ends fixed to the lower frame. 18. The battery pack frame as claimed in claim 1, wherein at least one side of the inner side of the upper frame and the inner side of the lower frame includes an elastic fixing portion thereon, the elastic fixing portion fixing ends of each elastic member of the plurality of elastic members to the at least one inner side of the upper frame or the lower frame. 19. The battery pack frame as claimed in claim 1, wherein each elastic member of the plurality of elastic members has a coiled spring structure.
