Abstract

PURPOSE:To enhance the magnetizing force of an engaging member and to protect the outer periphery of a permanent magnet by integrally securing the permanent magnet and a ferromagnetic plate with a cylindrical nonmagnetic case having an inner peripheral edge collar and exposing the end face of the permanent magnet from the end face of the cylindrical case. CONSTITUTION:A step 1b is formed on the outer peripheral surface of a permanent magnet 1 having an engaging hole 1a, the permanent magnet 1 is inserted into the nonmagnetic cylindrical case 4 formed with an inner peripheral edge collar 4a to be engaged with the step 1b, a ferromagnetic plate 2 and a washer 5 are inserted, and a pawl 4b formed in the case 4 is bent fixedly. Thus, the end face of the magnet becomes the same plane as the end face of the case 4, the opposite ferromagnetic plate can be attracted without gap on the magnetic pole surface, thereby enhancing the magnetizing force and protecting the magnet with the cylindrical case.
