Abstract
A fuse block 1 includes a fuse box 2 and a high voltage fuse 3. The fuse box 2 has a high voltage mounting part 6. The high voltage mounting part 6 is provided with an opening 6a, a plurality of surrounding walls 7a, 7b, and projections 8. Each of the projections 8 is projected from both the surrounding walls 7a, 7b which are adjacent to each other into an interior of the high voltage mounting part 6. A rated voltage fuse cannot be mounted to the high voltage mounting part 6 because of the presence of the projections 8. The high voltage fuse 3 includes a housing 10 having outer walls 14a, 14b and recesses 13. Each of the recesses 13 is formed by displacing both the outer walls 14a, 14b which are adjacent to each other. When the high voltage fuse 3 is mounted to the high voltage mounting part 6, the recesses 13 and the projections 8 will not interfere with each other.
