<p><P>PROBLEM TO BE SOLVED: To provide a structure, capable of avoiding situations where a computing unit for computing the quantity of state in a state assembled to an automobile fails due to exposure to rainwater, slurry, dust, high temperature, etc. even when the computing unit is integrally provided with a rolling bearing unit. <P>SOLUTION: An electronic circuit board 10, the computing unit, is arranged inside a cylindrical cover 5a with a bottom. The cylindrical cover with the bottom is fixed to an axial-direction inner end part for blocking an axial-direction inner-end opening of an outer ring 1. The periphery of the electronic circuit board 10 is covered with a sensor holder 9a, a thermosetting resin 23, or the like. By adopting such a structure, problem is solved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
