To facilitate mounting and removing work of a sensor in a bearing device with a rotation speed detector, and achieve firm attachment of a sensor onto a sensor holder.
A bearing device with a rotation speed detector which allows attachment of a head of a sensor 12 onto a sensor holder 6 by elastic force of a clip piece 16 is provided with the clip piece 16 so as to be openable and closable in the front/rear direction by a rotating shaft 16b fitted to an lower end. By integrally forming the bottom 16a with the lower end of the clip piece 16 and pushing the sensor 12 into a sensor inserting part, a clip piece 16 integrated with the bottom 16a is rotated to the back side to be closed, and a locking part 16c of the clip piece 16 is fitted into a stop groove 12a on the front of the sensor 12, so that the sensor is fixed. By deflecting the clip piece 16 towards the front and removing the locking part 16c of the clip piece 16 from the stop groove 12a on the front of the sensor 12, the bottom 16a integrated with the clip piece 16 is rotated upward, so that the sensor 12 is pushed out of the sensor inserting part.
