A press roller apparatus for an equipment of cutting a brittle material has a delivery frame ascended and descended and linearly moved along a crack line by a roller driving device; a wheel rotatably mounted to the delivery frame; and an elastic ring detachably connected to a periphery of the wheel and closely contacted with a surface of the brittle material. According to the apparatus, only the elastic ring is closely contacted with a surface of the brittle material. Thus, when there occurs a damage during cutting the brittle material, it only has to re-tool the elastic ring only without a re-tooling of the wheel.
