Disclosed herein is a spacer used in a battery pack having a plurality of battery cells mounted in a pack case, wherein the spacer is configured to have a top shape corresponding to the inner shape of the pack case in vertical section and a bottom shape corresponding to the outer circumferential shape of the battery cells in vertical section so that the spacer can be mounted in a space defined between the battery cells and the pack case, grooves, in which electrical connection members are mounted, are formed at the top of the spacer, and the spacer includes at least one temperature detection member mounting part including a horizontal opening open in one direction or in opposite directions and a vertical opening communicating with the horizontal opening so that a temperature detection member is inserted from one side of the spacer and mounted in a space defined between the battery cells. In the spacer, the temperature detection member is inserted into the horizontal opening from one side of the spacer so that the temperature detection member can be fixed between the battery cells and the spacer, and therefore, a process of bonding the temperature detection member is omitted. Also, the electrical connection members for electrical connection between the battery cells and between the battery cells and a protection circuit member are mounted in the grooves so that the electrical connection members are fixed in an insulated state, thereby preventing the occurrence of a short circuit due to vibration or impact and simplifying an assembly process.

Disclosed herein is a wireless device including at least one locker structure. The locker structure includes a battery pack side coupling member (a first coupling member) protruding from the outer surface of a battery pack, the first coupling member having a hook formed at one side thereof and a structure tapered downward toward the battery pack (an incline structure) at the other side thereof, and a wireless device body side coupling member (a second coupling member) mounted in a body of the wireless device at the position corresponding to the first coupling member, the second coupling member including a coupling part which can be coupled with the hook, a member body having a rear protrusion formed at the position corresponding to the incline, and an elastic member mounted at the rear of the member body. When the member body is pushed toward the elastic member so as to separate the battery pack from the wireless device, the coupling part is uncoupled from the hook, and the rear protrusion pushes the incline of the first coupling member. As a result, the battery pack is automatically separated from the wireless device.
