In a spindle device, a cover member covers a surface of a flange portion on the front side of the spindle shaft, the flange portion projecting radially outward from the outer peripheral surface of the spindle housing, and the outer peripheral surface of the spindle housing extending from the surface of the flange portion toward the front of the spindle shaft. In the cover member, a flow path for allowing a coolant to flow therethrough is formed.
