To provide a shaving device capable of accurately shaving the surface of a workpiece by exactly deviating a processing tool along the surface of the workpiece.

A shaving device 100 comprises: a grinder 101; and a work holding part 132. The grinder 101 is supported by a support part 110 at a state of holding a processing tool 103 consisting of a grindstone for shaving an outline OL of a workpiece WK consisting of a vehicular hub to perform deburring. The work holding part 132 attachably/detachably holds the workpiece WK to be rotated and driven by a work drive motor 133. The support part 110 supports the grinder 101 at a rotatable state so that a tool holding part 102 which holds the processing tool 103 in the grinder 101 rotates and deviates toward the side of the work holding part 132 by self-weight. The processing tool 103 which rotates and deviates toward the side of the work holding part 132 is separated from the workpiece WK by actuation of a tool saving mechanism 120.
