Disclosed are a device with stabilization base and a video display apparatus. The stabilization base is movable between a use position and a storage position, and is locked in the use position so that it would not easily move. When no problem occurs even if the stabilization base is moved, the locking of the stabilization base in the use position can be canceled easily. The stabilization base () is movable between the use position where it is projected outwards in relation to an outer edge of a grounding portion of an apparatus main body () and the storage position where it is stored on the inner side in relation to an outer edge of the apparatus main body. The stabilization base in the use position is immovably locked by lock means (), () provided in the apparatus main body, and the locking by the lock means is canceled by pressing from the lower side or a lateral side.

The invention is directed to provide a rolling method which enables an enlarged range of reduction ratio in sizing-rolling in the common drive system. The invention provides that when tension applied to rolled material between the upstream and downstream-placed mills is made higher than a value that tension/average resistance to deformation of rolled material is 0.2, the upstream-placed mill is caused to perform force rolling, and when compressive force of the rolled material is made higher than a value that compressive force/average resistance to deformation of rolled material is 0.1, the downstream-placed mill together with the upstream-placed mill are caused to perform tensile rolling in the common drive system. The rolling methods provides a stable rolling in a larger sizing range without decrease of diameter or buckling of rolled material.

Rolling mill driving mechanism

A rolling bearing, in which at least one of the races and a rolling element of the rolling bearing is made of a raw steel which is free from a Al.sub.2 O.sub.3 or an Al.sub.2 O.sub.3 -base inclusion particle with a 13 .mu.m or more average particle size; but which includes 80 or less Al.sub.2 O.sub.3 or Al.sub.2 O.sub.3 -base inclusion particles with a 3 .mu.m or more average particle size for each tested area of 165 mm.sup.2. The rolling bearing provides a very long life rolling bearing even under the severe conditions of a high bearing, the presence of a deflection in a bearing housing, defective lubrication, etc.
