る。(F) Embodiment FIG. 1 is a sectional view showing a main part of an embodiment of the present invention.
A feature of the present invention is that the protrusion (11) is formed in the pole piece (2) by being fitted into the protrusion (6) of the sealing metal (4). Therefore, the strength of the protrusions (6) of the sealing metal (4) is increased and the permanent magnets (8) are not crushed. Therefore, the permanent magnet (8) is prevented from adverse thermal effects.
