Abstract
There is provided magnetizing apparatus and magnetizing method for a magnetized pulser ring, by which magnetic force to which a cylindrical elastic magnetic member is magnetized can be enhanced, and yet in which centering of a magnetizing yoke is easy to achieve. A magnetizing portion of the magnetizing yoke is a conical surface slightly tilted with respect to an axis thereof. The magnetizing yoke is inserted into a cylindrical steel plate of the magnetized pulser ring so that the magnetizing portion of the magnetizing yoke is brought into close contact with one axial end portion of the cylindrical elastic magnetic member.
