Abstract
PURPOSE:To reduce a distance between two ball bearings to simplify the assembly of a bearing device so as to aim at its cost reduction by generating the pre-pressure of the ball bearings by the repulsive force of magnet members. CONSTITUTION:Disc-like annular-seat-shape magnet members 5 are fitted to the face sides where ball bearings 3, 4 face each other and each magnet member 5 has the same magnet polarity on each face confronting the other in an axial direction. Accordingly, a distance between two ball bearings 3, 4 is reduced and its assembly is simplified and its cost can be reduced.
