<p>PURPOSE: To simplify the structure of a base by forming an axial positioning means to be kept into contact with a fixed ring member of a bearing device, and an elastic means acting on a detector for radial positioning, so that the detector is brought into cotnact with the base. CONSTITUTION: A bearing device 10 comprises a rotary inner ring member 1, a fixed outer ring member 2, and plural rolling elements installed between the ring members 1 and 2. The bearing device 10 is sealed by a packing 4. Further, an inspection device comprises a stationary detecting element 11, and a code element 12 rotatable with the rotary ring member 1 through a deflector 5 of the packing 4, and the information on rotation from the code element 12, is detected by the detecting element 11. The element 11 is accomodated in an attachment head 110, a guide device such as a groove 111, is formed on a side surface of the head 110, and a transverse groove 112 which accomodates a rib member for holding the head 110 in the circular base and positioning the same, is formed on a front face of the head 110.</p> |
