Title: BATTERY PACK
Abstract:
The present invention prevents a thin fuse link (3C) from breaking due to an impact or vibrations, and improves the impact resistance of a battery pack. Each metal-plate busbar (3) electrically connects a plurality of batteries disposed at fixed positions in a battery holder (2), and includes: fixed terminals (3A) connected to electrode terminals of the batteries; a base portion (3B) connecting the fixed terminals (3A); and fuse links (3C) respectively coupling the fixed terminals (3A) and the base portion (3B). In the base portion (3B) of the busbar (3), a first fitting portion (3I) is provided to a fuse link coupling portion (3Ba) that is coupled with the neck portion of the fuse link (3C). A second fitting portion (2C) coupled to the first fitting portion (3I) is provided to the battery holder (2). The second fitting portion (2C) is coupled with the first fitting portion (3I), and the fuse link coupling portion (3Ba) is coupled to the battery holder (2) so as not to move relative thereto.
