Accordingly, provided is a double swing indoor opening and closing apparatus for a bus, in which a first door arm and a second door arm rotate in conjunction with a respective operation of a first air cylinder and a second air cylinder and enable a first door and a second door to rotate by means of a first door fixing link and a second door fixing link respectively so as to open and close an entrance door. The double swing indoor opening and closing apparatus for a bus is processed in such a manner that the first door arm and the second door arm are connected integrally between an upper portion of a first connecting rod in the first air cylinder connected to the first door arm and an upper portion of a second connecting rod in the second air cylinder connected to the second door arm, and the first door and the second door rotate when the first air cylinder and the second air cylinder operate by installing a link unit to synchronize a rotary speed of the first door arm and the second door arm. |
