  • Patent number: 10510507
    Abstract: A fuse unit includes a fusible link, a holding mechanism, and a locking mechanism. The fusible link is connected to a battery terminal and includes a fusible element that melts when an overcurrent flows through the fusible link. The holding mechanism includes a base portion disposed between a post standing surface of a battery housing and the battery terminal in a state where the battery terminal is fastened to a battery post provided on the post standing surface, and a holding portion that is formed next to the base portion and that holds the fusible link above the post standing surface. The locking mechanism locks the holding mechanism onto the post standing surface. With this configuration, the fuse unit can suppress a load acting on the battery post.
