An equipment for supporting a molten steel supply nozzle in a twin roll strip caster is provided to prevent skull from being generated on a surface of molten steel during casting and seek operational stability by preventing external air from flowing into the nozzle when moving the nozzle upward during casting and easily changing the height of the nozzle using a nozzle supporting device. An equipment for supporting a molten steel supply nozzle(140) in a twin roll strip caster comprises: a nozzle supporting structure(210) for supporting the molten steel supply nozzle that is attached to a lower part of a tundish(130) of the twin roll strip caster and vertically passes through a central part of the tundish; a sealing plate(230) which is airtightly contacts an outer part of a sidewall of the nozzle supporting structure and connected and fixed to meniscus shields(160) through a sealing wool(232); and an LM guide(220) including an external block fixed perpendicularly to the bottom of a bracket of the nozzle supporting structure such that LM guide which is vertically linked with the nozzle supporting structure, and an internal block fixed perpendicularly to an upper surface of the sealing plate, the LM guide having a spring formed on an outer peripheral surface thereof to enable a vertical lot reciprocating motion of the LM guide, wherein at least two gas exhaust ports(231) are formed in the sealing plate.
