かつた。 However, in this case, during assembly, the first reduction gear 1a and the pinion 6 slide in the axial direction and mesh with each other. 5, the teeth of the pinion 6 came into contact with the teeth of the first reduction gear 1a in the axial direction, causing damage to the tooth profile. To overcome this drawback,
It is conceivable to attach the motor body 5 to the case 2, but this reduces the flexibility of the assembly process, and avoids the same disadvantages described above when replacing the motor body 5 due to a defect in the motor after assembly. I couldn't do it.

る。 On the other hand, the motor main body 20 has a built-in synchronous motor having a rotor and a stator (not shown), and has a pinion 21 connected to the rotor projecting upward. This motor main body 20 is inserted in the direction of arrow A into the storage part 11 of the case 10 in which the reduction gear group 16 is assembled. At this time, the pinion 21 slides in the guide groove 12 and meshes with the first reduction gear 16a in the interaxial direction, and even if the teeth contact each other, either the pinion 21 or the first reduction gear 16a is slightly It rotates to eliminate the unreasonable engagement. At the same time, the claws 15, 15 engage with the corners 22 of the motor body 20, thereby preventing the motor body 20 from coming off. Positioning of the motor body 20 in the insertion direction (direction of arrow A) is performed by the side surface 23 of the motor body 20 coming into contact with the inner side surface (not shown) of the storage section 11.
