Battery pack for electric power tool

摘要

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.

主权项

1. A battery pack for an electric power tool that is detachably mounted on a tool body of the electric power tool for serving as a power source for the electric power tool, the battery pack comprising:
a case; battery cells; and a cell holder that is inserted into the case, the cell holder covering at least a part of the battery cells, wherein a dimensional difference interposition member serves to bridges a dimensional difference between the cell holder and the inside of the case by generating a pressing force applied to the case when the cell holder is inserted; the dimensional difference interposition member being molded integrally with the cell holder; and the dimensional difference interposition member is formed as a cutout in the cell holder, and serves to bridge the dimensional difference by the elasticity thereof when the cell holder is completely inserted into the case.
