A fastener is provided having a tapered surface cut out outwardly toward the tip on the upper inner surface of the side portion corresponding to the second fastening plate portion, and between the two side portions of the fastener, Insert the lower part of the first and second fastening plates of the terminal body and Screw from the top through the screw hole of the fastener through the bolt hole of the terminal body, the fastener rises at the time of the tightening, and the tapered surface of the side tightens the protrusion of the second tightening plate with the first tightening A battery terminal is provided in which the electrode fitting portion is pressed against and fixed to the outer peripheral surface of the battery post by pressing toward the plate portion side.

When the lower portions of the first and second tightening plates of the terminal body are inserted between both sides of the fastener as described above, and the bolts are tightened from above, the tightening tool rises. Since the second fastening plate is pressed toward the first fastening plate via the tapered surface provided on one side of the fastening tool and the tapered protrusion of the second fastening plate, the electrode The fitting portion can be pressed and fixed to the outer peripheral surface of the battery post. That is, since the tightening is performed from directly above instead of the tightening from the lateral direction, the tightening operation can be performed without taking a space at the time of fastening and fixing, and the workability is improved.

The terminal body has a substrate portion extending from the electrode fitting portion on the side opposite to the side on which the first and second tightening plate portions extend, and electric wires are connected to the substrate portion. It is preferable to provide a stud bolt for projection and / or a barrel for crimping an electric wire (claim 2). With this configuration, the terminal connected to the electric wire can be fastened and fixed to the stud bolt with a nut, or the electric wire can be directly crimped and connected to the barrel for crimping the electric wire. It is preferable that an LA terminal (a crimp terminal provided with a bolt hole) connected to a starter motor and / or an alternator is connected to the stud bolt of the board portion.

The terminal body has a substrate portion extending from the electrode fitting portion on the side opposite to the side on which the first and second fastening plate portions extend, and a plurality of holes are formed in the substrate portion. It is preferable to provide a bolt hole or a nut embedding portion for connection with one end of a plate-shaped fuse. With this configuration, the plate-shaped fuse can be directly connected to the battery terminal, and the fuse can be easily connected to the battery as compared with the case where the fuse is connected to the fuse box via a lead wire.
