WIPO Patent Application WO/2016/181515

A1

Provided are a magnetic encoder and a rolling bearing, whereby sealing properties of a fitting part of a slinger and a rotary member can be increased, and productivity equal to that of the prior art can be maintained. A magnetic encoder (15) is provided with: a slinger (20) having a cylindrical part (20a) capable of fitting in a rotary member (11), and a flange part (20b) extending in a radial direction from the cylindrical part; and a substantially annular magnetic part (21) multi-pole magnetized in the circumferential direction and attached to the outside surface of the flange part of the slinger by an adhesive; the magnetic part having a protruding part (22) protruding further than a fitting surface (20e) of the cylindrical part in the radial direction, the protruding part being formed so as to span an R part (20d) of the cylindrical part, a linear part (20c) of the cylindrical part, or a linear part from the R part of the cylindrical part, the protrusion thickness (t) of the protruding part is set to 1 to 20% of the plate thickness of the cylindrical part, and by fitting of the slinger in the rotary member, the protruding part is pinched between the rotary member and the cylindrical part of the slinger and interposed in a wedge shape therebetween.
