Goggle Brace (ゴーグルブレス Gōguru Buresu): The Goggle-V's transformation device. To transform, they call their name (the team name if the whole team; individual names for individual members). The activation of the brace summons the Goggle Suit for usage which surrounds the user with the energy of their gemstone on the helmet; if not authorized to use it, the energy will merely shock the user as what happens to a Spotman after trying to use Goggle Yellow's brace.
The braces are individualized by number (similar to the number of "lines" requires to make the shapes of their gemstones) as well as an LED light that glows in the color of their gemstone.
The braces themselves do not contain either the Goggle Suit or the powers of Goggle V; they are merely communication devices and relays for retrieving the Goggle Suit. The brace can be destroyed but it will not lead to a loss of power, merely inconvenience the user and prevent them from using any of their powers of Goggle V until they receive another brace.
At the climax of the Legend War, the Goggle Braces were made redundant when Goggle V sacrificed their powers with the rest of the first 34 Super Sentai to destroy the invasion force of the Space Empire Zangyack. Resurfacing as Ranger Keys, the Goggle V powers would be used by the Gokaigers to assume their forms via the Gokai Change. Ultimately, the Gokaigers returned their borrowed powers to their rightful owners after overthrowing Zangyack.
- The Goggle Brace is the first Transformation device sold as a toy; thus possibly explaining its simpler design (being merely a wrist-watch like object with a faceplate) compared to the more ornate Vulcan Brace of the previous season.
