Abstract:
1. A rolling bearing device comprising: an inner ring including an outer peripheral raceway surface for a rolling element; an outer ring including an inner peripheral raceway surface for said rolling element, the outer ring being engaged with and fixed to a fixing member; and a vibration isolating member that includes a laminated body comprising a pair of metal layers and a resin layer interposed between the metal layers, the vibration isolating member being disposed between the fixing member and the outer ring, the pair of metal layers extending over distal end faces of the resin layer such that the pair of metal layers contact each other at the distal end faces of the resin layer, wherein the vibration isolating member includes a vibration isolating part which is press clamped between an end surface of the outer ring at a preloaded side in an axial direction and a bottom surface of a concave part formed in the fixing member, in such a manner that a direction of lamination coincides with the axial direction, wherein the vibration isolating member includes an auxiliary vibration isolating part which is arrant d between an inner peripheral surface of the concave part and an outer peripheral surface of the outer ring, in such a manner that the direction of lamination coincides with a radial direction of the outer ring, wherein the vibration isolating member is in a form of a vibration isolating sleeve in which the vibration isolating part including the pair of the metal layers and the resin layer is integrally coupled to the auxiliary vibration isolating part including the pair of the metal layers and the resin layer, in an L-shape, and wherein resin layer sealed parts in which a pair of said metal layers are directly brought into tight contact with each other for sealing the resin layer are respectively formed in a circumferential direction, at an inner peripheral edge part of the vibration isolating part in the radial direction and at an end edge part of the auxiliary vibration isolating part at a side not connected to said vibration isolating part in the axial direction.
