A battery cover () covers an outer periphery of a fuse unit () connected to, through a battery terminal (), a battery post () projecting in a recess () formed on an upper surface () of a battery (). The battery cover () has a fuse cover part () covering the outer periphery of the fuse unit (), and a terminal cover part (). The terminal cover part () is connected to the fuse cover part () to be capable of being opened and closed, is arranged in the recess (), and covers the battery post () and the battery terminal (). The terminal cover part () is provided with a regulating portion () so as to regulate a movement of the terminal cover part () in a closing direction by coming in contact with the upper surface () of the battery ().

Battery cover

In a fuse circuit body according to an embodiment, electricity generated by an alternator is supplied to a first battery from an alternator connecting portion via a first fusible portion and a first battery connecting portion and supplied to a second battery from the alternator connecting portion via a second fusible portion and a second battery connecting portion. Thus, the electricity from the alternator is supplied to the first battery only via the first fusible portion and supplied to the second battery only via the second fusible portion. Accordingly, the electricity supplied from the alternator to the first battery or the second battery is not required to pass through two fusible portions so that the electricity can be supplied to the first battery and the second battery with a small loss.

Fuse circuit body for vehicle

A first battery connecting end, an alternator connecting end and a second battery connecting end of a circuit body are located at an upper surface portion of a unit body.

Fuse unit

An alternator connecting bolt of an alternator connecting end has a diameter different from that of a second battery connecting bolt of a second battery connecting end.
