特徴とする鉛蓄電池用端子としたことである。Means for Solving the Problems In order to solve the above-mentioned technical problems, the technical means taken in claim 1 of the present invention is a lead-acid battery terminal for connecting a lead-acid battery and an external load. The lead-acid battery terminal includes a metal terminal member having a bolt head portion, a conductive member fitted to the bolt head portion, a fitting portion fitting the conductive member, and a pole in the lead-acid battery. A lead bush having a bush portion that is in electrical contact with the pillar, wherein the bolt head portion and the conductive member are fitted in an intricate state to form a lead-acid battery terminal. .

And the contact angle with the contact surface is 45 °
It fits in the state described above. " That is, referring to FIG. 10 exemplarily illustrating the concept of the present invention, when a tightening torque is applied to a terminal unit (not shown), the bolt head unit
For example, in FIG. 10, a force is applied to rotate clockwise. At this time, the angle between the direction vector B to which the force is applied and the contact surface A on the contact surface A between the conductive member and the bolt head portion is represented by θ. The direction vector B of the force is decomposed into a direction vector C in which the force acts in the direction in which the bolt head is turned and a direction vector D in which the force acts in the direction in which the bolt head slides, as shown in FIG. Here, if θ is 45 ° or less, the direction vector D in which a force acts in the direction in which the bolt head slides increases, and the bolt head tends to slide. On the other hand, when θ is 45 ° or more, the direction vector C in which a force acts in the direction in which the bolt head is turned increases, and the sliding force is small. Therefore, θ is 45 °
If the fitting is performed in the complicated state as described above, the sliding and the sliding are reduced, and the tightening strength can be secured.
