Title:
MOTOR
Document Type and Number:
Japanese Patent JP2020034105
Kind Code:
A
Abstract:
To provide a motor which can easily fix a support plate for supporting a bearing so as to adjust concentricity.SOLUTION: A motor 1 includes a rotor 3, a stator 4, a bearing 5a, a holding member 2b and a support plate 6a. The holding member 2b holds the bearing 5a. The support plate 6a supports the bearing 5a so as to adjust concentricity. The holding member 2b has a plurality of protrusion parts 7 extending toward the support plate 6a. Each of the plurality of protrusion parts 7 has a first protrusion part 71 and a second protrusion part 72. The first protrusion part 71 has an elastic force and extends in the axial direction. The second protrusion part 72 extends in the extension direction D crossing the axial direction from the first protrusion part 71. The second protrusion part 72 has a slide surface 721. The slide surface 721 is further separated from the first protrusion part 71 in the extension direction D as it comes closer to the support plate 6a. The support plate 6a has an edge part 11. The edge part 11 comes into contact with the first protrusion part 71 in the extension direction D.SELECTED DRAWING: Figure 6
