取付け環体。[Claims for Utility Model Registration] (1) A rotating drum, a rotating shaft that is placed at the center of the rotating drum and rotates together with the rotating drum, and a rotating shaft that is attached to the rotating shaft via a bearing and that approaches the rotating drum. A VTR comprising: a lower drum disposed coaxially with the rotating shaft; a mounting ring inserted into the rotating shaft and attached to the rotating shaft with an end face abutting an end face of the bearing; and a motor rotating the rotating shaft.
A mounting ring for a VTR drum assembly, characterized in that the mounting ring includes a deformable portion that allows the end face of the mounting ring to be deformed to conform to the end face of the bearing. (2) The mounting ring for a VTR drum assembly according to claim 1, wherein the deformed portion of the mounting ring is a slit. (3) The deformed portion of the mounting ring includes a pair of slits formed facing inward from the outer surface of the mounting ring, and a slit formed from the outside to the inside that is different from the pair of slits by approximately 90 degrees and different in the axial direction. A mounting ring for a VTR drum assembly according to claim 1, which is comprised of another pair of slits formed to face each other.
