Double Typhoon (ダブルタイフーン Daburu Taifūn): Kamen Rider V3's first and foremost weapon - the transformation belt "Double Typhoon". Shiro Kazami transforms into V3 by performing the "Henshin", a series of moves which activates the 2 revolving pistons of the Double Typhoon, and then converts the accumulated wind energy to transform Kazami into Kamen Rider V3. Kamen Rider V3 is powered by the energies of the right "Kamen Rider #1 Typhoon" and the left "Kamen Rider #2 Typhoon". This allows V3 to utilize both the "Skill" of #1 and the "Strength" of #2.
- In the filming process, New 2's Typhoon have some small holes but New 1's Typhoon doesn't have.
- The colour of the fans in the Typhoon belts that Kamen Sentai Gorider wear match the colour of their respective members.
- Ever since Kamen Rider × Super Sentai: Super Hero Taisen, the number of red buttons on the front-facing side of the Typhoon was reduced from four on each side to two.
