Abstract: A charger (40; 240; 340) charges a battery pack (20) that is detachably attachable to a cordless power tool (12). The charger has at least a first side wall (44b) that at least partially defines a battery pack receiving hole (44; 244) shaped to receive and accommodate the battery pack. A charging output element (62; 362) supplies charging power to the battery pack. The battery pack receiving hole has a lateral cross sectional area that decreases downwardly in the vertical direction of the battery pack receiving hole such that gravity causes the battery pack to be guided to a prescribed position within the battery pack receiving hole. In addition, the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position.

Abstract: A front pressing rib is formed integrally with the cell holder. The front pressing rib bridges a dimensional difference between the inside of the case to be assembled and the cell holder by generating a pressing force on the front side. That is, the cell holder is pressed rearward in the case by a pressing force of the front pressing rib that is applied to the inside of the case. The front pressing rib serves to completely bridge the dimensional difference when the cell holder is inserted into the case.
