PROBLEM TO BE SOLVED: To provide an end face plate capable of preventing leakage of resin without using a sealing pin and a pin moving mechanism.SOLUTION: There is provided an end face plate 30 mounted on an upper end face of a yoke 15 which is provided with a magnet insertion hole 24 into which permanent magnets 14 are inserted and an excessive hole 25 which parallelly extends from the magnet insertion hole 24 and is provided integrally with the magnet insertion hole 24. The end face plate 30 is integrally equipped with exhaust nozzles 32 to be inserted into the excessive hole 25. Air residual on a bottom of the magnet insertion hole and the excessive hole can be evacuated. There is no worry of resin leakage without air. Because the exhaust nozzles are provided, leakage of resin can be prevented without using a sealing pin and a pin moving mechanism.
