First claim

Opening claim text (preview).

What is claimed is: 1. A charger comprising: a plurality of battery attachment portions to each of which a battery pack is detachably attached; a main body housing that includes a recessed portion on a corner of two side surfaces of the main body housing, the two side surfaces intersecting each other and the recessed portion being inwardly recessed in a side surface in a top view of the main body housing; and a power source cord that is configured to be directly drawn out from an opening provided in the recessed portion without using a protective member for the power source cord, wherein: at least one of the plurality of battery attachment portions is configured such that the battery pack is attached to and detached from the corresponding battery attachment portion in an oblique direction with respect to a horizontal direction by a sliding operation of the battery pack along a top surface of the corresponding battery attachment portion; and the recessed portion is opened upwards in a height direction of the main body housing, thereby enabling the power source cord that is configured to be directly drawn out from the opening of the recessed portion to extend upwards in the height direction of the main body housing when both of the two side surfaces of the main body housing are brought into contact with wall surfaces. 2. The charger according to claim 1 , wherein the recessed portion is provided over an entire area in the height direction of the main body housing, the recessed portion being opened both upwards and downwards in the height direction. 3. The charger according to claim 1 , wherein each of the plurality of battery attachment portions is configured such that a terminal cover for covering a connection terminal provided on each of the plurality of battery attachment portions is detachably attached to the corresponding battery attachment portion. 4. The charger according to claim 1 , wherein the battery pack is used for an electric power tool. 5. The charger according to claim 3 , wherein the battery pack is used for an electric power tool.
