Claims

[Claims for Utility Model Registration] 1. A gear device that transmits the rotation of a motor to an output shaft, and this gear device has a worm wheel part that meshes with an input side worm and a worm part that meshes with an output side gear. In a motor actuator having an integrally formed intermediate gear, at least one support shaft of the intermediate gear is covered with a cap-shaped bearing, and this bearing is received by a bearing portion of a case, the bearing is attached to the case. A motor actuator characterized by being provided with a fixing means for fixing. 2 The fixing means has at least two
Two elastic tongues are formed to spread from the side surface of the cylinder to both sides, and the elastic tongues are pressed against the side surfaces of the bearing section of the case, and the elastic tongues are locked to the bearing section of the case by the elasticity of the elastic tongues. The motor actuator according to claim 1, characterized in that the motor actuator has a locking structure. 3. The fixing means includes an inclined bottom surface of the bearing, an inclined end surface of the bearing portion of the case corresponding to the bottom surface of the bearing, and a fitting means for fitting the bottom surface of the bearing onto the end surface of the bearing portion. The motor actuator according to claim 1, characterized in that the motor actuator has a mating structure. 4. Utility model registration claim 3, characterized in that the fixing means has a pressing structure in which a spring is interposed between the support shaft of the intermediate gear and the bearing, and the spring presses the bearing against the end surface of the case. Motor actuator as described. 5. The fixing means includes a flange portion provided on the bearing,
Request for registration of a utility model characterized in that the flange portion has a chamfered portion, a guide groove is formed in the bearing portion of the case, and the chamfered portion of the flange portion is engaged with the guide groove to prevent rotation. The motor actuator according to the ranges 1 to 4.
