Description of the Related Art Conventionally, for example, a fuse box of an automobile is provided with a fuse for preventing an abnormal current from flowing in an electric circuit, but a fuse of the type shown in FIGS. 16 and 17 is used. Have been. That is, the fuse 1 has a conductive portion 2 stamped and formed from a conductive metal plate. When an excessive current flows through the narrow portion 2b connecting the pair of tabs 2a, 2a, the narrow portion 2b is blown and cut off the current. The upper half of the conductive portion 2 is covered with a mold portion 3 molded from an insulating resin material. A total of four concave grooves 4 extending in the up-down direction are formed on both front and rear side surfaces of the mold portion 3. Furthermore, the concave groove 4
Steps 5 are formed at the upper ends of the pulleys, respectively, so that pullers 6 to be described later are engaged.

[0003] A fuse 1 of the type described above can be arranged closer to each other than a conventional fuse in which a conductive metal wire is arranged inside a glass tube. Thus, the fuse box can be reduced in size, but a special puller is required to remove the fuse from the fuse box.

An example of such a puller will be described with reference to FIGS. 16 and 17. The puller 6 includes a cylindrical main body 7 which can be fitted to the mold portion 3 of the fuse 1,
