PURPOSE: A laminated rotor core of a motor is provided to prevent a shaft and a rotor core member from running idle, thereby facilitating easy press-fitting of a shaft. CONSTITUTION: A laminated rotor core comprises a rotor core member(10), a shaft(20), and at least one or more keys(21). The rotor core member includes a shaft hole extended to a direction of a rotation shaft and a key groove communicating with the shaft hole. The shaft is press-fitted into the shaft hole. A key accommodation groove is concavely formed at a peripheral position corresponding to that of the key groove. The at least one or more keys is formed at the key groove and the key accommodation groove to restrict the rotor core member and the shaft. |
