Claims

[Scope of Claim for Utility Model Registration] (1) First and second semicircular cases whose circumferential ends are joined to form an annular shape, and which are provided in the inner circumferential direction of the first and second cases. In the split-type ammeter, the first case is provided with recesses at both circumferential ends thereof, and the second case is fitted with the recesses at both circumferential ends thereof. A split-type ammeter, characterized in that a mating convex portion is formed, and both ends of the iron core in the circumferential direction provided in the first and second cases are overlapped with each other to form a shape that can be freely fitted. (2) First and second semicircular cases whose circumferential ends are joined to form an annular shape, an iron core provided in the inner circumferential direction of these first and second cases, and a case wound around the iron core. In the split type ammeter, a recess is formed at both ends of the first case in the circumferential direction, and a convex part that fits into the recess is formed at both ends of the second case in the circumferential direction, Further, both ends in the circumferential direction of the iron cores provided in the first and second cases are overlapped with each other so that they can be freely fitted, and a fixture is further provided to maintain the joined state of the first and second cases. A split-type ammeter characterized by:
