<P>PROBLEM TO BE SOLVED: To provide a magnet coupling structure of a high temperature-high pressure roots blower for vulcanizing a tire, for preventing reduction in the demagnetization action by a temperature rise and the magnetic force action by a rise up to the Curie temperature of a magnet coupling used for the high temperature-high pressure roots blower for vulcanizing the tire. <P>SOLUTION: A magnet coupling 200 includes a recessed part 8 in its inner coupling 2, lubricating oil 14 in an oil case 16 enters the inside of this recessed part 8, and the inner coupling 2 is sufficiently cooled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
