The Fourze Driver is Kamen Rider Fourze's transformation belt that was given to Gentaro by Kengo Utahoshi. To transform into Fourze, Gentaro places four Astroswitches into the Switch Sockets and flips the red switches down to begin the countdown. Afterwards, he pushes the Enter Lever on the side of the belt and raises his right arm in the air. By switching on a correspondent Astroswitch, or a combination of Astroswitches, before pushing the Enter Lever again, Fourze can perform a Limit Break finishing attack.
While executing a Double Limit Break is possible, it is risky as it would completely drain an Astroswitch's power for a while, rendering one of them useless until they are completely recharged.
History
The Fourze Driver was invented by the father of Kengo Utahoshi, based on his research in Cosmic Energy. The Circle, Cross, Triangle, and Square Basement designs were based off of the pillars in Kyoto, where Utahoshi and his team researched the Hole over the city.
Future
5 years later, Gentaro tries his best to pursue Sanagiman into redeeming himself even destroying the belt by throwing it on the molten lava at a factory as a sign of truce. He later borrows the Fourze Driver from his present day self to fight alongside Wizard. After the future Gentaro returns to his own time, Haruto gives the Driver back to the Gentaro of the present.
Cosmic Enegy
Cosmic Energy is the power of the universe and the source of power of both the Astroswitches and the Zodiarts Switch. Depending on how Cosmic Energy is channeled and made, it can do a lot of things, from allowing Gentaro and Ryusei to transform into their Rider forms to even healing severe sicknesses and overcoming death itself. The most powerful Zodiarts Switches and Astroswitches derive their power from the 12 Western Zodiac constellations and the laws of the universe.
Magnet Switch Carrying NS MagPhone

The Magnet Switch Carrying NS MagPhone has two functions. It can be split into N Magnet Switch and S Magnet Switch, and inserted it into the Fourze Driver to access Magnet States. When inserted in the Driver, they are used as joysticks to control the Magnet Cannon Modules. When both parts are attached, it can be used as a phone.
It's also an important part of the two Magnet Switches, because without it, Fourze can't access Magnet States and only access the Magnet Modules, which are uncontrollable. In terms of Fourze's gear, only the MagPhone serves as a second "transformation" device for Gentaro to achieve a new States.
History
Gentaro had asked rookie Kamen Rider Club member Ryusei to lighten Kengo's load at the Rabbit Hatch by helping out with the adjustment of the Magnet Astro Switches. Ryusei mistakenly declares the switches ready-for-use, much to Kengo's protest. Tachibana discovers the error in the process and secretly provides Ryusei with the schematics for a controller device, which will suppress the magnet switches to the degree of being usable.
Kengo is jealous that Gentaro would entrust his work to a rookie. Ryusei goes ahead and builds the NS Magphone and again declares it ready. However, the device won't work (it won't divide in two), much to Ryusei and the club's shock. Kengo was still upset that Magphone wasn't finished yet. When Ryusei confronts Kengo to fix things with Gentaro (using magnets as a metaphor), Kengo realizes what adjustments have to be made with the phone. Once successful, Fourze was able to achieve Magnet States.
