Claim 0:
1. A battery pack comprising a battery cell, an input/output terminal to/from which a charging/discharging current of the battery cell is to be inputted/outputted, a connector detachably connected to the input/output terminal; and an elastic connection member arranged between the input/output terminal and the connector, wherein
the input/output terminal comprises a base portion, a first hollow conductive member protruding from the base portion in a first direction, and a second hollow conductive member protruding from the base portion to surround an outer periphery of the first hollow conductive member,
the connector comprises a central guide protruding in a second direction opposite to the first direction, and a third hollow conductive member protruding to surround an outer periphery of the central guide,
the central guide is fitted into a hollow portion of the first hollow conductive member, and
the third hollow conductive member is fitted into a space between the first and second hollow conductive members and is electrically connected to the first and second hollow conductive members by the elastic connection member arranged in the space between the first and second hollow conductive members such that the elastic connection member contacts each of an outer circumferential surface of the first hollow conductive member and an inner circumferential surface of the third hollow conductive member and further contacts each of an inner circumferential surface of the second hollow conductive member and an outer circumferential surface of the third hollow conductive member.
