Claims

[Scope of utility model registration request]

A laminated core for the rotor is installed on the rotor shaft through a keyway formed on the rotor shaft and a key inserted into the keyway, and this laminated core is mounted on the rotor shaft. In a rotor of a rotating electric machine, a rotor shaft is provided with a stepped portion that prevents the key from moving toward at least one side, the stepped portion of the rotor shaft and the end of the keyway being relatively close to each other. The key which is formed at a large distance and inserted into this key groove is a stepped key in which a corner on the rotor shaft side of one end thereof is cut off, and the one end of the stepped key is The stepped key is inserted into a keyway of the rotor shaft so that the remaining portion of the key extends along the rotor shaft toward the stepped portion of the rotor shaft. Electric machine rotor.
