PROBLEM TO BE SOLVED: To provide a reduction gear having a motor capable of providing high rotation accuracy and rotation surface accuracy in an output shaft when the motor is mounted to the reduction gear. SOLUTION: This reduction gear having the motor comprises a partitioning member 13 disposed between the motor 11 and the reduction gear 12 for decreasing the rotation speed of the motor and transmitting it to the output shaft, a support body 14 for supporting the reduction gear, an input gear 17 for inputting the rotation of the motor into the reduction gear, a first bearing 18 disposed between one end of the input gear and the output shaft 15, and a second bearing 19 disposed between the other end of the input gear and the partitioning member. Both end surfaces 13a and 13b of the partitioning member are formed flat, respectively, and the partitioning member is mounted to the reduction gear so that one end surface 13a abuts on a plane 20a of the reduction gear and a plane 14a of the support body, respectively.
