Rubber cover main bodies (42) close opening shapes of terminal-connection openings when a battery pack (10) is placed alone without being mounted on a tool body. When the battery pack (10) is removed from the tool body and is placed alone, it is possible to regulate the entry of foreign materials, such as water or dust, by the rubber cover main bodies (42). Further, when body-side connection terminals (91, 92, and 93) are connected to battery-side connection terminals (36), the rubber cover main bodies (42) themselves can be deformed due to elasticity according to the slide movement of the body-side connection terminals (91, 92, and 93) such that the body-side connection terminals (91, 92, and 93) can be inserted into the rubber cover main bodies (42). Accordingly, it is possible to protect the battery-side connection terminals (36) in the terminal-connection openings such that the battery-side connection terminals (36) are not damaged by regulating the entry of foreign materials, such as water or dust, from the terminal-connection openings without hindering electrical connection caused by slide mounting. |
