PROBLEM TO BE SOLVED: To ensure an insulation distance as prescribed while enhancing the workability.SOLUTION: An attachment mechanism includes cases 11a, 11b having an aperture 22 formed therein, a conductor 13 inserted into the aperture 22 and an insertion hole 1a of a current detection part 1, a pair of bus bars 14 having distal ends 14a coupled with ends 13a, 13b of the conductor 13, respectively, and proximal ends 14b attached to an attachment object, and supplying a current to be measured to the conductor 13, and a bolt 15 for coupling the distal end 14a of each bus bar 14 and the ends 13a, 13b of the conductor 13, respectively. The conductor 13 has a non-circular columnar cross-sectional shape and is provided with a screw hole 33, respectively, in the ends 13a, 13b. The apertures 22 of the cases 11a, 11b are formed, respectively, in such a shape as rotation of the conductor 13 thus inserted can be regulated. The bolt 15 is configured so that it is inserted into a coupling hole 41 of each bus bar 14, and can be screwed into each screw hole 33 of the conductor 13. |
