Patent ID: 7237960

Claim:
A method of mounting a magnetic encoder on an outer periphery of an encoder carrier member by press-fitting, wherein the magnetic encoder comprises a multipolar magnet formed of a sintered element and having a plurality of alternating magnetic poles alternating with each other in a direction circumferentially thereof; and a core metal supporting the multipolar magnet, the sintered element being prepared by sintering a powdery mixture of a magnetic powder and a non-magnetic metallic powder; the sintered element being fixed on the core metal by means of a staking technique to provide a sintered element/core metal assembly; and an anticorrosive resinous coating formed over an entire surface of the sintered element/core metal assembly by means of a surface treatment, which method comprises: when the magnetic encoder is press-fitted on the outer periphery of the encoder carrier member, heating one of a press-fitting punch and the magnetic encoder to a temperature within the range of 60 to 150° C.
