|This article is about a/an transformation device in Kamen Rider 555.|
Designated SB-000B, the Transformation Belt Orga Driver (変身ベルトオーガドライバー Henshin Beruto Ōga Doraibā), also known as the Belt of the Emperor (帝王のベルト Teiō no Beruto), is an ornate belt that generates the photon streams for the Kamen Rider Orga armor. If the belt is removed, the armor disappears. The belt straps of the Orga Gear were made of leather rather than metal; a leather holster was strapped onto its right side.
The Orga Driver was presumably destroyed following the death of its user, Yuji Kiba.
World of Faiz
The Orga Driver also existed in the A.R. World of Faiz, but was unused. Having given the Faiz Driver back to Takumi Ogami, Daiki Kaito (Kamen Rider Diend) stole the Orga Driver from the ruins of Smart Brain High School as his treasure from that world.
