Claims

[Scope of utility model registration request]

It is equipped with a multi-row roller bearing that rotatably supports the shaft body, a bearing box in which the multi-row roller bearing is assembled, and a support body in which the bearing box is assembled, and the axial direction of the ears provided on both the left and right sides of the bearing box In a multi-row roller bearing device in which the axial movement of the bearing box is restricted by bringing both end surfaces into contact with the support surfaces of the support, the axial end surfaces of the ears of the bearing box on the shaft end side and the support. A curved surface is formed on at least one of the support surface of the ear and at least one of the axial end surface of the ear of the bearing box on the shaft body side and the support surface of the support. An alignment device for a bearing box in a multi-row roller bearing device, characterized in that the bearing box is supported in the axial direction in line contact, point contact, or curved surface contact with a support surface.
