<p><P>PROBLEM TO BE SOLVED: To enable a yoke and a frame member to be fixed without rattling and surely prevent noise generation caused by the rattling. <P>SOLUTION: An engaging concave part 33 recessed in a radially inward direction of the yoke 21 is provided between a magnet 26 and a radial bearing 31 which are arranged in an axial direction of the yoke 21, each elastic deformation piece 53a that elastically deforms radially in a first frame member 50 is provided at opposite sides of the first frame member 50, and each engaging convex part 53b that engages with the engaging concave part 33 to fix the first frame member 50 to the yoke 21 is provided to the elastic deformation piece 53a. Accordingly, the yoke 21 and the first frame member 50 can be fixed without rattling, and can surely prevent noise from a seat motor 10. Further, by checking an elastic deformation state of the elastic deformation piece 53a, it can be confirmed whether the engaging convex part 53b is properly engaged with the engaging concave part 33, and a false assembly can be prevented and productivity can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
