Patent attributes
A motor includes a bearing having first and second end faces spaced along a longitudinal axis thereof. A longitudinal hole extends from the first end face through the second end face and includes a recessed portion having first and second peripheral edges respectively contiguous to the first end face and an inner periphery of the longitudinal hole. A retaining member is mounted to the first end face. A radial spacing between an inner periphery of a through-hole of the retaining member and the inner periphery of the longitudinal hole of the bearing in a radial direction is not greater than an axial spacing from the first end face to the second peripheral edge. The retaining member further includes a plurality retaining plates. The recessed portion provides a space sufficient to allow deformation of the retaining plates when inserting a shaft through the through-hole into the longitudinal hole of the bearing.
