Abstract: PURPOSE:To realize a lightning equipment which prevents a scattered object from being produced easily when an inner surface of a hollow hole is short- circuited and is simple-structured by forming a fragile part which is incorporated into the lightning equipment and breaks foremost when discharging voltage of the lightning equipment. CONSTITUTION:In a lightning element 1a with a non-linear voltage-current characteristic, a hollow hole 4 which is concentric with a central axis is formed. A fragile part 6 is formed in a bottom direction of a V-character shaped notch 5 which is provided at one side of the hollow hole 4. When a large amount of current flows to a lightning element 1a by receiving a great shock and short- circuiting the hollow hole 4, temperature within the hollow hole 4 rapidly increases and an inner pressure increases. A notch 5 whose section is in V- character shape is formed at the lightning element 1a and a crack is developed extensively from a bottom part of the notch 5 and is damaged readily in two- division state from a fragile part 6. Cracks are generated while the inner pressure does not increase, are divided into two, and are damaged. Inner gas is promptly discharged breaking through a rubber material 14 readily, and the breakage is not explosive without causing any dangerous objects to fall down.
