PROBLEM TO BE SOLVED: To provide a bearing mechanism in which a cylinder portion is hardly deformed even if a radial bearing is pressed in a frame, by improving a holding structure of the radial bearing in the frame, and a motor device equipped with the bearing mechanism.SOLUTION: In a bearing mechanism 7, radial bearings 71 and 72 are made from resin, and equipped with cylinder portions 711 and 722 rotatably supporting a worm 2 (a rotary shaft), and flange portions 712 and 722 expanding diameters from the cylinder portions 711 and 721 to the outside in a diametrical direction. The flange portion 712 is pressed in between two wall surfaces 611 and 612 of a slit 610 of the frame 6, and the flange portion 722 is pressed in between two wall surfaces 621 and 622 of a slit 620 of the frame 6. A cover 9 is formed with grooves 910 and 920 at least partially storing a part projecting out from the slits 610 and 620 of the flange portions 712 and 722. |
