Abstract
A wheel speed detecting device includes a countermeasure against the entrance of muddy water. An annular recess groove is provided in an outer circumference of an end portion of a hub on a sensor side. A cup-shaped flange portion extends from the sensor supporting member with the flange portion covering the annular recess groove while maintaining a predetermined gap Tbetween the flange portion and the outer circumference of the end portion of the hub. Muddy water heads toward a multi-pole magnet ring by running through the gap Tformed between the flange portion and the outer circumference of the hub. However, the entrance of muddy water can be effectively prevented by making the gap Tsmall. Thus, muddy water that enters the gap Tis trapped in the annular recess groove.
