Abstract
A battery pack charger including a case () having an attachment section () where a battery pack () can be attached in a detachable manner, and a plurality of connecting terminals () disposed in an exposed manner in the attachment section to connect with external terminals () on the battery pack. The connecting terminals are disposed in approximately vertical orientation in a plurality of approximately parallel rows. The case has terminal through-holes () opened through the case between adjacent connecting terminals. Even if there is ingress of foreign material, such as dust and dirt, between the connecting terminals, that material can fall through the holes in the case. Foreign material collection between the connecting terminals can be avoided, and the battery pack charger has the positive feature that unintended conduction, such as leakage current and short-circuit, can be avoided.
