Abstract:
An axial direction sliding-contact type brush apparatus is provided which can not only maintain performance of suppressing vibration of a brush of a flat vibrator motor but also allow the brush to form a stable electrical contact with a commutator. The base portion of the brush is installed at the exposed portion of the pattern of the brush base above the bracket at an elevation angle of 45° or less with respect to the brush base. The ultraviolet-cured acryl-based resin is coated on the base portion of the brush to cover a position located at about ⅓ of the side projection length L of the brush arm portion from the base portion of the brush.
