PROBLEM TO BE SOLVED: To provide a battery pack for power tools in which a backlash of a cell holder relative to a case after the cell holder is assembled to the inside of the case is suppressed while assemblability of the cell holder to the inside of the case is excellently maintained.SOLUTION: In a cell holder 50, a front-side press rib 541 is provided integrally therewith. The front-side press rib 541 fills a dimensional difference between the inside of a case 11 to which the cell holder 50 is assembled and the cell holder 50 by generating a pressing force on the front side. This means that the cell holder 50 is pressed toward the back inside the case 11 by a pressing force of the front-side press rib 541 against the inside of the case 11. The front-side press rib 541 acts so as to fill the dimensional difference immediately before assembling of the cell holder 50 to the inside of the case 11 is completed. Also, the front-side press rib 541 acts so as to thoroughly fill the dimensional difference when the assembling of the cell holder 50 to the inside of the case 11 is completed. |
