Claims

[Claims for Utility Model Registration] ■ An inner ring 62 of a bearing 6 is fitted into one end of a rotating shaft provided in a housing, an outer ring 61 corresponding to the inner ring 62 is fitted into a housing, and an adjustment screwed into the housing. In the bearing preloading mechanism that presses the outer ring in the axial direction with the screw thrust of the screw 7, a contact protrusion 81 is provided between the bearing 6 and the adjustment screw 7 in the center of the surface on the adjustment screw 7 side and comes into contact with the screw 7. A preloading device for a rolling bearing, in which an intermediate member 8 is interposed, the other surface of which has a contact surface 82 that abuts against the outer ring 61 and protrudes along the outer ring 61. ■ The housing is the lower cylinder 3 of the upper and lower cylinders 4 and 3 that constitute the cylinder unit of the video tape recorder, and the rotating shaft 2 is for rotating the video head. Preload device for rolling bearings. (2) The preload device for a rolling bearing as set forth in claim 1 or 2 of the registered utility model, in which the top of the contact protrusion 81 is a ball. (2) The preload device for a rolling bearing according to any one of claims 1 to 3 of the utility model registration claim, wherein the contact surface 82 is formed in an endless shape.
