    Abstract: The present invention relates to a spindle device that supplies a prescribed amount of a lubricant agent intermittently or continuously from a lubricant supply device (3) to a rolling bearing (2) via a supply pipe (4), wherein the lubricant includes a lubricating oil and wax and, when a liquefaction point, which is a prescribed temperature within a temperature range of 10-70 °C, is used as a boundary, assumes a liquid state when the liquefaction point is exceeded and assumes a semisolid state when at or below the liquefaction point, and the lubricant is transported from the lubricant supply device (3) in a semisolid state via the supply pipe (3), and is changed to a liquid state before the rolling bearing (2) and caused to flow into the bearing interior.
