<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing device and the rolling bearing device with a pressure regulating device capable of achieving high sealing performance in an environment of rainy weather or the like and providing sealing performance at low friction torque when traveling in general. <P>SOLUTION: The rolling bearing device 1 is equipped with the tire pressure regulating device 8 which includes a raindrop sensor 17 for detecting a raindrop, a compressed fluid supply source 9 connected so as to fill annular space 2f of the rolling bearing device 1 with compressed fluid, and a control device 15 for controlling the compressed fluid supplied to the annular space 2f from the compressed fluid supply source 9 when the raindrop sensor 17 detects a raindrop. The annular space 2f of the rolling bearing device 1 is connected and communicates with the tire air chamber 5b of a tire 5c constituting a wheel 5 so that the pressure of the compressed fluid supplied to the annular space 2f can be regulated by the tire pressure regulating device 8. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
