PROBLEM TO BE SOLVED: To provide a motor actuator of which the durability is increased without increasing the cost. SOLUTION: This motor actuator has fixing ribs 16a and 16b on a lower case, which are formed by being extended from the lower case 12, and the fixing ribs 16a and 16b respectively receive bearing sections 15a and 15b which are provided on both end surfaces of a micromotor 13. In addition, a fixing rib 16d (a fixing rib 16e is not shown in the figure) which respectively supports the bearing sections 15a and 15b together with the fixing ribs 16a and 16b is formed on an upper case which is placed over the lower case 12 and fixes the micromotor 13 in a manner to pinch it as well. The fixing rib 16d is arranged in a manner to be overlapped with the fixing rib 16a from outside in the axial direction of the micromotor 13. Thus, the fixing rib 16a is reinforced so as to withstand an impact load in the axial direction. COPYRIGHT: (C)2006,JPO&NCIPI
