ELECTRIC CURRENT MEASURING DEVICE WITH IMPROVED INSTALLABILITY
First Claim
1. A current measuring device for measuring an electric current flowing through between a terminal of a battery and a wire, the current measuring device comprising:
- a resistance member having a length and first and second ends in a direction of the length, the first end being to be secured electrically to the terminal of the battery, the second end being to be secured electrically to the wire, the resistance member constituting a current flow path between the terminal of the battery and the wire, the resistance member having a turned portion through which the current flow path extends; and
a circuit board in which a current measuring circuit is installed, the current measuring circuit being configured to measure an electric current flowing through the resistance member based on a potential difference between two different points defined on the resistance member.

Abstract
In a current measuring device for measuring an electric current flowing through between a terminal of a battery and a wire, a resistance member has a length and first and second ends in a direction of the length. The first end is to be secured electrically to the terminal of the battery. The second end is to be secured electrically to the wire. The resistance member constitutes a current flow path between the terminal of the battery and the wire. The resistance member has a turned portion through which the current flow path extends. The current measuring device includes a circuit board in which a current measuring circuit is installed. The current measuring circuit measures an electric current flowing through the resistance member based on a potential difference between two different points defined on the resistance member.
