Abstract: A battery post terminal assembly includes a battery post terminal including a grasping portion capable of grasping a battery post on an inner side, and a fastening portion placed in a form of a pair to extend from end portions of the grasping portion, a holder placed on one side of the fastening portion, and a base member placed on an opposite side to the holder with the fastening portion between the holder and the base member. The base member has a base seat portion, a screw shaft that is provided on one surface of the base seat portion to be coupled to the holder, and a projection portion that is provided on a surface having the screw shaft of the base seat portion, and to project to an inner side of the fastening portion when coupled to the holder.

Abstract: A battery state detection device (1) includes a shunt resistor (7) and a battery post terminal (4). The shunt resistor (7) includes a second conductor part (12) in the shape of a flat plate. The battery post terminal (4) includes a battery post connecting part (20) for connection to a battery post, and a shunt resistor connecting part (22) for connection to the second conductor part (12) of the shunt resistor (7). The shunt resistor connecting part (22) is in the shape of a flat plate. The second conductor part (12) of the shunt resistor (7) and the shunt resistor connecting part (22) of the battery post terminal (4) are connected to each other by welding.

Abstract: A fixing structure includes a battery post terminal having extended portions each having an inclined surface formed thereon, and an electrode fitting part sandwiching, from both sides, side surfaces of a battery post by performing pressing to narrow a space between the extended portions; a slope member having four leg parts each having a slope formed thereon whose inclination angle is the same as that of the inclined surface, and pressing the extended portions by being moved in an up-and-down direction while making the slopes to be brought into contact with the inclined surfaces; and a bolt moving the slope member in the up-and-down direction, in which the four leg parts are disposed with a space provided therebetween along an outer periphery of a screw part, the screw part being set as a center, when the battery post terminal is seen from a vertical direction.
