MOTOR
Document Type and Number:
Japanese Patent JP2019161800
Kind Code:
A
Abstract:
To provide a motor capable of reducing cost by simplifying a structure of a bearing portion.SOLUTION: In a motor 1, an outer peripheral surface of a first cylindrical portion 115 of a rotary shaft 11 is directly and slidably supported by a cylindrical portion 75 formed on a metal end plate 70 located on an output side La of a stator 20 in a first bearing portion 7. The rotary shaft 11 is slidably supported by a substrate holding member 30 located on a counter-output side Lb of the stator 20 in a second bearing portion 3. The substrate holding member 30 includes a resin body 30a that holds a substrate 60, and an inner peripheral surface of a second cylindrical portion 117 of the rotary shaft 11 is directly and slidably supported by a cylindrical portion 35 of the resin body 30a. For this reason, it is not necessary to use expensive ball bearings for the first bearing portion 7 and the second bearing portion 3.SELECTED DRAWING: Figure 3
