Abstract

Provided is a motor actuator which prevents the rotation of a motor by using a simple structure, and the vibration of the motor is not easy to transfer to a casing. A motor (20) disposed in the upper and lower casings (11,12) of the motor actuator is provided with a motor casing (21) and a motor casing cover (22), and the bottom (21A) of the motor casing and the motor casing cover (22) are respectively provided with two recessed portions (26). The recessed portions (26) clamp the rotating shaft of the motor (2) and are disposed above and below the assembling direction of the upper and lower casings (11,12), the inner sides of the upper and lower casings (11,12) are respectively provided with two motor support portions (3) composed of vertical rib plates. The two motor support portions (30) of the lower casing (12) are fastened with the recessed portions (26) below, the two motor support portions (30) of the upper casing (11) are fastened with the recessed portions (26) above, and the motor in non-contact with the bottom surfaces of the upper and lower casing is supported.

Description

technical field [0001] The present invention relates to a mounting structure of a motor of a motor actuator. Background technique [0002] A motor actuator driven by a motor is known as a drive source for an air damper valve of an air-conditioning apparatus used in a vehicle such as an automobile (for example, Patent Document 1). [0003] The motor actuator as Figure 7 As shown, a motor 104 having a rotating shaft 103 is accommodated inside a housing formed by assembling a case main body 101 and a cover 102 . The bearing accommodating portion 105 of the motor 104 is directly sandwiched by the motor support portion 106 provided at the case main body 101 and the cooperative support portion 107 provided at the cover 102 . Furthermore, in order to prevent the rotation of the motor 104, the rotation prevention support part 108 which abuts on the motor 104 is uprightly provided in the inner surface of a case. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2009-201325...
