摘要：
A structure for fixing a permanent magnet in a rotor core. The structure includes a magnet accommodation portion into which a permanent magnet is to be inserted, an internal hole formed in an area adjacent to one end of the magnet accommodation portion, a pressing portion provided between the magnet accommodation portion and the internal hole. The pressing portion forms a convex shape toward the permanent magnet to be in contact with the permanent magnet.
