Namely, cylindrical sidewall portion 131a is vertically outstanding and to be formed and therein by chimeric and hold and the inscape of rigid bearing 120 from the upper side of bearing fixed part supporting bracket 132, and as required, cylindrical sidewall portion 131a and upper surface part 131b or stop part 131c is integrally formed or is formed separately, thus the inscape that can play a kind of effect can be comprised further, this effect to prevent the bearing 120 be inserted in cylindrical sidewall portion 131a from moving towards the upper side opening direction of cylindrical sidewall portion 131a because of applied force when carrying out the movement of falling object along back shaft 230.
Upper surface part 131b is formed with hole that back shaft 230 passes through and the mode of the upper side of the sidewall of inner space that the back shaft 230 being namely wrapped to form the center being configured at bearing 120 with the upper side of wrapping up bearing 120 the inserts inscape that vertically extends from the upper end of cylindrical sidewall portion 131a one and formed, as a specific implementation example, upper surface part 131b can be that be formed with the through hole identical with the diameter of back shaft 230, identical with the diameter of bearing 120 circle flat board.Stop part 131c is with the inscape formed in the mode of the upper side of wrapping up bearing perpendicular to the mode of cylindrical sidewall portion 131a is formed, stop part 131c can not form as one with cylindrical sidewall portion 131a, as long as stop part 131c is formed at the side wall upper part face of the bearing 120 be inserted in cylindrical sidewall portion 131a and can prevents from bearing 120 from moving towards the upper side opening direction of cylindrical sidewall portion 131a just can using known all formations.
Bearing fixed part supporting bracket 132 can be categorized as Fig. 2 a and the first kind combined as an example illustrated only contact with the upper surface part face of circuit board 110 like that in Fig. 2 b, contact with the most of face of the upper surface of circuit board 110 as illustrated in Fig. 3 a is routine as one with in Fig. 3 b and the Second Type that combines.With regard to the first kind, bearing 120 by support component 130 to combine and under the state being fixed on circuit board 110, owing to only there being the upper surface of circuit board 110 part central part upper surface that especially through hole is in place to contact with bearing fixed part supporting bracket 132, thus cost can be saved.In addition, compared with Second Type, the first kind combines because circuit board 110 is contacted by face with coil 140, thus can thicken coil thickness further and improve platypelloid type motor performance further.In contrast, Second Type due to bearing 120 by support component 130 combine and be fixed on circuit board 110 state under combine with the upper surface of circuit board 110 major part, thus there is the advantage that more can firmly fix bearing 120.
Being shown with Fig. 2 a and Fig. 2 b and Fig. 5 a of a specific implementation example of the bearing fixed part supporting bracket 132 of the first kind from figure, following scheme can being proposed to the shape of bearing fixed part supporting bracket 132: being the narrow band shape of width from being positioned at one end of bearing fixed part supporting bracket 132 of rear end of bearing fixed part 131 and leading section 132b to bearing fixed part 131 part in place centered by bearing fixed part 131; To the shape be positioned at the other end of bearing fixed part supporting bracket 132 of front end of bearing fixed part 131 and rearward end 132a be, first from the band shape that the part that bearing fixed part 131 is in place is narrow in width to certain length, what then expand gradually in width to the other end and rearward end 132a of bearing fixed part supporting bracket 132 is fan-shaped.If have this shape, then fan shape part and circuit board 110 widely contact and improve the bed knife of bearing 120 in face, and the part that coil configures exposes thus can thicken the thickness of coil, and weighing body 150 is combined with the upper surface of fan shape part, thus bearing 120 can be made to be combined with circuit board 110 more securely.In addition, although not shown, but the weighing body fixed projection formed along the direction bending vertical with bearing fixed part supporting bracket 132 is possessed in the outer peripheral edges of fan shape part, thus support component 130 and weighing body 150 can not only be made to combine securely, and the separating force putting on weighing body 150 when rotor 100 rotates because of centrifugal force can be weakened.
Illustrated in figure is shown with in Fig. 3 a of a specific implementation example of the bearing fixed part supporting bracket 132 of Second Type and Fig. 3 b and Fig. 5 b, bearing fixed part supporting bracket 132 can be formed with the shape almost identical with circuit board 110, has to make bearing fixed part supporting bracket 132 shape be combined with almost most of upper surface of circuit board 110.
