BATTERY PACK, ELECTRIC TOOL AND CHARGER

摘要

PROBLEM TO BE SOLVED: To provide a battery pack mounting structure which can minimize the influence of increasing friction resistance due to roughness of the slide surface and is almost free from defects even when left and right operation loads are deviated.SOLUTION: Two operation members 40 installed on both sides of a battery pack 10 are provided in order to operate an engaging member 30. The engaging member 40 includes: an operation part 42 enabling push-in operation; a spindle part 43 installed in the operation part 42; and a depression part 41 extended to a position of abutting on a receiving part 32 of the engaging member 30. When push-in operation is performed inward, the operation part 40 is rotated around the spindle part 43 as an axis and moves the engaging member 30 in the projecting direction by depressing the receiving part 32 by the depression part 41.
