PROBLEM TO BE SOLVED: To curtail the number of parts by causing a cylindrical substance united into a body with a box body, slits formed in the cylinder, a lamp fitted to the cylinder, and electric wire fixing claws united with the box body into a body to fix an electric wire connected between the lamp and a circuit breaker, constitute a current flow indicating unit. SOLUTION: A circuit breaker housing box 1 is provided with a box body 2, a circuit breaker 3, a lid, an opening provided at an opposing spot of the lid to the operating handle 3a of the circuit breaker 3, a cover which covers the operating handle 3a of the circuit breaker 3, and a flow displaying part 7 for displaying the flow of a current to the circuit breaker 3. The flow displaying part 7 is constituted with a cylinder 8 united with the box body 2 into a body, slits 9 formed in the cylinder 8m a lamp 10 fitted to the cylinder 8, and electric wire fixing claws 12 formed into a united body with the box body 2 to fix an electric wire 11 connected between the lamp 10 and the circuit breaker 3. Consequently, it becomes possible to curtail the number of parts. |
