Abstract
A pulser ring has cylindrical inner and outer rings nested together. The inner ring is formed at its one end with protrusions arranged at equal angular intervals. The outer ring is in the shape of a round comb and has its teeth engaged at a portion near the tip thereof in the grooves defined between the adjacent protrusions formed on the inner ring. The tip of each tooth protruding from the grooves is bent radially inwardly so as to engage the end face of the protrusion on the inner ring, thus coupling the inner ring and the outer ring together.
