The spindle device is rotatably supported by a housing, and a lubricating oil supply gap is provided in the through hole of the main shaft, and the drive rod of the tool gripping means is passed through at a position corresponding to the bearing. A seat is provided, and the spacer is movable in the axial direction according to the stroke of the drive rod, and has annular oil grooves on its inner and outer surfaces, as well as a radial oil passage for communicating the oil grooves. , an oil groove on the outer surface of the spacer and a radial oil supply hole provided in the inner ring of the bearing are communicated via a radial oil supply path provided in the main shaft, and the oil groove on the inner surface of the spacer is connected in the axial direction of the drive rod. A spindle device that allows oil to be supplied to the bearing from the end of the main shaft, which communicates with an oil supply path that extends from the main shaft end.
