ABSTRACT:
A glass cutting apparatus has a spindle rotatably held and a saw blade provided on the spindle at a tip portion thereof. An upper portion of the blade is covered with a top cover. A lower portion of the blade, which protrudes from a lower portion of the top cover downward, is covered with a swingably safety cover held through a second ball bearing provided at an outer periphery of a bearing case. A fixing member between the bearing case and the blade is provided with a seal cover member which has a tip portion extending to the neighborhood of an outer periphery of a seal member for covering the bearing. Thereby, the seal cover member covers the seal member on a blade side thereof. Thus, the glass-cutting apparatus can eliminate a danger of touching its saw blade by mistake at the time of non-operation.
