Abstract

This ring speed detector is constructed of a magnetic sensor and a magnetic ring and is integrated with the inside of a seal device. The magnetic ring constitutes a part (core bar) of the seal device. This arrangement can enable the compacting and reduction in the number of components and improve space saving and assembling workability.
