Abstract: PROBLEM TO BE SOLVED: To realize easy compatibility with reduction in size and weight by enhancing rigidity of a case without lowering molding accuracy of the case.SOLUTION: A motor storage part 24 includes a reinforcement rib 24d extending from one end in an axial direction of the motor storage part 24 to the other end in the axial direction. The reinforcement rib 24d is arranged on the side where a caliper fixing part 23 of the motor storage part 24 exists. Therefore, rigidity of a case 21 is enhanced, and it can be suppressed that the caliper fixing part 23 and the motor storage part 24 are twisted with each other when an electric motor 30 is driven. The size and weight of the case 21 can be reduced, and also, generation of operation sound and change in backlash of a gear of a speed reduction mechanism 50 can be suppressed. Even when the case 21 is produced by injection molding with resin material, it can be suppressed that the motor storage part 24 falls down to the side of caliper fixing part 23 due to shrinkage and the like, thus molding accuracy of the case 21 is improved, problems in manufacturing are overcome and the yield can be improved.SELECTED DRAWING: Figure 5
