定装置。[Claims for Utility Model Registration] A speed detector fixing device that fixes a speed detector that detects the rotational speed of a spindle to a bearing unit that rotatably supports the spindle via a bearing, the speed detector being attached to a speed detection ring. and a sensor unit, and a holder is provided which integrates a cylindrical part and a collar part having a small diameter part with a small inner diameter and a large diameter part with a large diameter, and the sensor unit is attached to the small diameter part of the holder. The holder and the sensor unit case are fixed by inserting a retaining ring from both sides of the sensor unit case to fix the holder and the sensor unit case at both ends of the small diameter portion, and the sensor unit is fixed to the outer periphery of the spindle via the gap. A speed detector fixing device characterized in that the collar of the holder is screwed to the case of a bearing unit so as to face the speed detection ring.
