  Next, an assembly procedure of the seat motor 10 formed as described above, in particular, a mounting procedure of the first frame member 50 to the yoke 21 will be described in detail with reference to the drawings.

  First, the second frame member 60 is mounted in advance on the motor main body 20 in which components such as the magnet 26 and the armature core 27 are incorporated (see FIG. 2), and the motor main body 20, the second frame member 60, and the like. Prepare the assembly. Next, the first frame member 50 is prepared, and as shown by the arrow A in FIGS. 3 and 4, each engagement of the yoke 21 is performed while matching the shapes of the yoke 21 and the first frame member (substantially hexagonal shape). The concave portion 33 and each engaging convex portion 53b of the first frame member 50 are aligned and moved close to each other.

  Then, each press-fitting rib 53d provided on the wall portion 53 comes into sliding contact with the yoke 21, and the press-fitting operation is continued. As a result, the first frame member 50 is positioned with respect to the yoke 21, and thereafter, each engagement convex portion 53 b rides on the frame member connection portion 24 of the yoke 21. Thereby, each elastic deformation piece 53 a is elastically deformed toward the radially outer side of the first frame member 50.

  Thereafter, when the first frame member 50 is further press-fitted into the yoke 21, the respective engaging convex portions 53 b enter the respective engaging concave portions 33. When each engaging convex portion 53b completely enters each engaging concave portion 33 and comes into close contact with each other, as shown by a broken-line circle B in FIG. 6A, each elastic deformable piece 53a is in a non-deformed state. By confirming the above, the mounting of the first frame member 50 to the yoke 21 is completed. Note that the concave-convex engagement between the respective engaging convex portions 53b and the respective engaging concave portions 33 can be easily confirmed from the outside by directly looking through the respective cutout windows 53c.

  Here, the length of the wall portion 53 along the axial direction is secured to some extent, and the mounting distance between the first frame member 50 and the yoke 21 is increased, thereby preventing rattling between the two. Since the joint convex portion 53 b is disposed at a substantially intermediate portion along the axial direction of the wall portion 53, each engagement convex portion 53 b is rapidly engaged with each engagement concave portion 33.

  When the mounting of the first frame member 50 to the yoke 21 is incomplete and each engaging convex portion 53b does not completely enter each engaging concave portion 33, as shown by a broken line circle C in FIG. Become. That is, each elastic deformation piece 53a remains elastically deformed toward the radially outer side of the first frame member 50. In this case, what is necessary is just to press-fit so that the 1st frame member 50 may be twisted with respect to the yoke 21, confirming the state of each elastic deformation piece 53a.

  As described in detail above, according to the seat motor 10 according to the present embodiment, each of the recesses inwardly in the radial direction of the yoke 21 between the magnet 26 along the axial direction of the yoke 21 and the radial bearing 31. An engagement recess 33 is provided, each elastic deformation piece 53a elastically deforming in the radial direction of the first frame member 50 is provided on the other axial side of the first frame member 50, and each engagement recess 53a is provided in each elastic deformation piece 53a. Each engaging convex part 53b which engages with 33 and fixes the 1st frame member 50 to the yoke 21 was provided.

  As a result, the yoke 21 and the first frame member 50 can be fixed without rattling due to the concave-convex engagement, and as a result, noise can be reliably prevented when the seat motor 10 is driven to rotate. Further, by confirming the elastic deformation state of each elastic deformation piece 53a, it is grasped whether or not each engagement convex portion 53b of the first frame member 50 is accurately engaged with each engagement concave portion 33 of the yoke 21. As a result, erroneous assembly of the seat motor 10 can be prevented and productivity can be improved.

  Further, according to the seat motor 10 according to the present embodiment, the first frame member 50 includes the wall portion 53 that covers the periphery of the frame member connection portion 24, and a substantially intermediate portion along the axial direction of the wall portion 53. Since each engagement convex part 53b is arranged in each, the engagement convex part 53b can be quickly engaged with each engagement concave part 33 while securing the mounting distance between the first frame member 50 and the yoke 21. Thereby, rattling of the yoke 21 and the first frame member 50 can be more reliably eliminated without reducing the productivity of the seat motor 10.

  Furthermore, according to the seat motor 10 according to the present embodiment, the engagement state between each engagement projection 53b and each engagement recess 33 is externally provided in the vicinity of each engagement projection 53b of the wall 53. Since each notch window 53c for confirmation is provided, the engagement state between each engagement protrusion 53b and each engagement recess 33 can be directly seen from the outside, and each engagement protrusion 53b and each The state of engagement with the engagement recess 33 can be grasped.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above embodiment, each notch window 53c is provided in the vicinity of each engaging projection 53b of the wall portion 53 so that the deformation state of each elastic deformation piece 53a can be more easily confirmed from the outside. Although shown, the present invention is not limited to this, and each notch window 53c can be omitted.

  Moreover, in the said embodiment, although what provided the several press-fit rib 53d in the wall part 53 was shown, this invention is not restricted to this, The 1st frame member 50 is omitted, omitting each press-fit rib 53d. You may make it lightly press-fit in the yoke 21. FIG.

  Furthermore, in the above-described embodiment, the yoke 21 and the first frame member 50 are attached to each other in a substantially hexagonal shape, but the present invention is not limited to this, and may be a circular shape. It is good also as polygonal shapes other than a hexagonal shape. Even if they are attached to each other as a circular shape, the yoke and the first frame member are prevented from rotating due to the concave-convex engagement of the engaging convex portions with the engaging concave portions, so that no problem occurs.
