This article is about a/an changer in Denshi Sentai Denziman.

Denzi Ring (デンジリング Denji Ringu): The Denzimen's transformation device. The transformation call is "Denzi Spark!" (デンジスパーク Denji Supāku).

The Denzi Ring is made of a hard material that will not open outside the command of the one who is in complete control of the transformation, only taking orders from whomever wears it. Any other methods to open the ring other than the user's command will ultimately fail.Ep. 11: Chase the Life-Stealer
