Claims

[Scope of utility model registration request]

(1) A capstan shaft provided with a flywheel, and a first shaft that rotatably supports this capstan shaft on the upper mounting board.
a radial bearing, a second radial bearing that rotatably supports the shaft end of the capstan shaft on the lower mounting board, an insertion groove formed toward the center of the second radial bearing, and the insertion groove. A capstan shaft support device comprising: a thrust bearing that is provided along the capstan shaft and supports the tip of the capstan shaft.

(2) 7. The capstan according to claim 1 of the utility model registration, characterized in that the insertion groove has a bearing portion at a position other than the second radial bearing portion to which a moment is applied via the capstan shaft. Axial support device.
