PROBLEM TO BE SOLVED : To provide a magnetic sealing member suitable for injection molding. SOLUTION : This magnetic sealing member 1 is formed in such a way that a yoke 3 which forms a magnetic circuit in a space between a magnet 2 and the yoke, and is made out of a soft magnetic body in a similar figure, is joined with one side of the magnet 2. As a whole, the magnetic sealing member 1 is formed out of a part roughly in a semi-cylindrical surface part 1a of a circular arc shape set by an angle of 120 deg. to 240 deg., and of a straight line shape part 1b. The magnet sealing member 1 is manufactured so as to allow the mixture of rare earth powder with resinous binder to be injected and formed integrally under high pressure in a forming metal mold at the inner bottom part of which the yoke 3 is positioned. |
