PROBLEM TO BE SOLVED: To reliably connect a positive electrode line and a negative electrode line to respective connection parts while polarities are adapted by making shapes of terminals of the positive electrode line and the negative electrode line connected to a positive electrode line connection part and a negative electrode line connection part of a terminal block device different from each other, and preventing flat plane parts from being properly located and screwed, when the terminal is connected to a connection part on a different polarity side.SOLUTION: A large diameter part is provided on any one of a pair of a positive electrode line 3 and a negative electrode line 4 at a portion near a terminal mounting part 23. Among a positive electrode connection part 5 and a negative electrode line connection part 6, an obstacle body 25 is provided at a connection part with other polarity different from one polarity. The large diameter part is located on the obstacle body to separate the connection part of the other polarity from the terminal with one polarity, so that the connection part of the other polarity cannot be connected to the terminal with one polarity. |
