MOTOR
Document Type and Number:
Japanese Patent JP2013027185
Kind Code:
A
Abstract:
To provide a motor that more effectively suppresses noise due to looseness of a bearing inside a through hole of a bearing holder.
In a motor 1, a bearing 7 is arranged inside a through hole 80 of a bearing holder 8 so as to be movable in a direction of a motor axis L. A flat spring portion 90 urges the bearing 7, as arranged in the through hole 80 of the bearing holder 8, toward a rotating shaft 51 and thus applies pressure to the bearing 7. A buffer layer 79, such as a grease layer or a rubber layer, is provided between an outer circumferential surface 72 of the bearing 7 and an inner circumferential surface 80a of the through hole 80.
