Claims

[Scope of utility model registration request]

(1) For fuses in which both ends of the insulating tube are sealed with caps and an indicator wire is stretched between the caps, which is a series connection of a fuse element and a fusible indicator wire and one resistance wire, the cap on the fuse indicator side is equipped with a conductive bottom plate. A fuse characterized by housing a spring and an indicator rod inside the sleeve, and attaching an insulating plate to the outside of the sleeve to display an indicator that can be fused and protruded by blowing the fusible wire.

(2) The fuse according to claim 1, which is a registered utility model, characterized in that the spring prevents the display bar from falling even if one end of the spring is passed through the hole in the display bar and the display bar protrudes.
