Abstract
A connection member connects a plurality of secondary battery cells when the secondary battery cells are mounted in a battery pack case. The connection member includes terminal connection parts connected to each other for connecting the battery cells. Each terminal connection part includes a first contact part, contacting the electrode terminal of a lower battery cell. An elastic pat tapers upward from the first contact part towards a central axis of each terminal connection part for elastically supporting the lower battery cell. Coupling parts protrude upward from the elastic part such that the protruding coupling pats are coupled to an electrode terminal of an upper battery cell. A second contact part is disposed on the central axis of each terminal connection part such that the second contact part is depressed from the protruding coupling parts, the second contact part contacting the electrode terminal of the upper battery cell.
