CONSTITUTION: A case(51) having a cylindrical shape includes an inlet which is opened in the horizontal direction. A bus bar conductor(61) is installed in the inside of the case. A molding conductor(63) is installed at a central conductor(59a,59b) which is disposed at a position apart from the inlet. One side of the bus bar conductor is slidably coupled with the molding conductor. A contactor(65) is coupled with the central conductor near the inlet. The contactor is coupled through a coupling unit to the other side of the bus bar conductor.
