Provided is a motor module including a motor and a planetary gear mechanism which is attached to an output shaft of the motor. The motor module includes a fixing portion that integrally fixes the motor and the planetary gear mechanism. The fixing portion fixes the motor by inwardly clamping the motor and fixes an internal gear of the planetary gear mechanism. ## Claims ### Claim 1 A motor module comprising: a motor and a planetary gear mechanism which is attached to an output shaft of the motor, and a fixing portion that integrally fixes the motor and the planetary gear mechanism to each other, wherein the fixing portion fixes the motor by inwardly clamping the motor and fixes an internal gear of the planetary gear mechanism, wherein the fixing portion fixes the internal gear thereto by inwardly clamping the internal gear thereto. ### Claim 2 (depends on 1) The motor module according to claim 1, wherein the internal gear has a flange portion which is formed so as to be widened in a flange shape in a direction away from the shaft center of the motor. ### Claim 3 (depends on 2) The motor module according to claim 2, wherein an outer diameter of the flange portion is formed so as to be substantially the same as an outer diameter of an end of the fixing portion on a planetary gear mechanism side. ### Claim 4 (depends on 2) The motor module according to claim 2, wherein an end of the fixing portion is in contact with the flange portion of the internal gear. ### Claim 5 (depends on 1) The motor module according to claim 1, wherein a planetary carrier of the planetary gear mechanism is configured to fix an eccentric shaft driving a pump of an ABS hydraulic unit in which anti-lock braking control of a hydraulic brake is performed. ### Claim 6 (depends on 1) An ABS hydraulic unit in which the motor module according to claim 1 is embedded and anti-lock braking control of a hydraulic brake is performed, the unit comprising: a block in which a pipeline of a hydraulic circuit connected to the hydraulic brake is formed, wherein an end of the fixing portion on a planetary gear mechanism side is fixed in the motor module so as to fit an inner face of a hole formed in the block. ### Claim 7 (depends on 6) The ABS hydraulic unit according to claim 6, wherein an internal gear is fixed so as to fit the inner face of the hole in the block. ### Claim 8 (depends on 6) The ABS hydraulic unit according to claim 6, wherein the end of the fixing portion is fixed by being clamped between the internal gear and the block. ### Claim 9 A motor module comprising: a motor and a planetary gear mechanism which is attached to an output shaft of the motor, and a fixing portion that integrally fixes the motor and the planetary gear mechanism to each other, wherein the fixing portion fixes the motor by inwardly clamping the motor and fixes an internal gear of the planetary gear mechanism, wherein an end of the fixing portion on a planetary gear mechanism side is formed so as to be widened in a flange shape in a direction away from a shaft center of the motor. ### Claim 10 (depends on 9) The motor module according to claim 9, wherein the internal gear has a flange portion which is formed so as to be widened in a flange shape in a direction away from the shaft center of the motor. ### Claim 11 (depends on 10) The motor module according to claim 10, wherein an outer diameter of the flange portion is formed so as to be substantially the same as an outer diameter of an end of the fixing portion on a planetary gear mechanism side. ### Claim 12 (depends on 10) The motor module according to claim 10, wherein an end of the fixing portion is in contact with the flange portion of the internal gear. ### Claim 13 (depends on 9) The motor module according to claim 9, wherein a planetary carrier of the planetary gear mechanism is configured to fix an eccentric shaft driving a pump of an ABS hydraulic unit in which anti-lock braking control of a hydraulic brake is performed. ### Claim 14 (depends on 9) An ABS hydraulic unit in which the motor module according to claim 9 is embedded and anti-lock braking control of a hydraulic brake is performed, the unit comprising: a block in which a pipeline of a hydraulic circuit connected to the hydraulic brake is formed, wherein an end of the fixing portion on a planetary gear mechanism side is fixed in the motor module so as to fit an inner face of a hole formed in the block. ### Claim 15 (depends on 14) The ABS hydraulic unit according to claim 14, wherein an internal gear is fixed so as to fit the inner face of the hole in the block. ### Claim 16 (depends on 14) The ABS hydraulic unit according to claim 14, wherein the end of the fixing portion is fixed by being clamped between the internal gear and the block.
