になつている。 On the other hand, between the upper surface of the flywheel body 1 and the lower surface of the bearing 2, a coil spring 10 is inserted between an upper washer 8 and a lower washer 9 and inserted into the capstan shaft 3.
is energized to the thrust receiver 6. A pair of protrusions 11 are provided on the periphery of the lower washer 9, facing each other.
11 is provided to protrude upward, and both protruding portions 11, 11
A pair of hole-shaped engaging portions 12, 12 are formed in the upper washer 8 correspondingly. This engaging part 1
A protrusion 11 is inserted into the upper and lower washers 8, 9 and the coil spring 10 so that they rotate together.

るために短筒状部である。 Note that the upper and lower washers 8 and 9 are made of synthetic resin with a low coefficient of friction, and rub against either or both of the flywheel body and bearing 2 that are in contact with each other, and the upper and lower washers 8 and 9 are rotated as one unit. It's becoming like that. In addition, 13 is a protrusion 11
The boss portion 14 forming an escape gap is a short cylindrical portion for housing and covering the upper and lower washers 8, 9 and the coil spring 10 and protecting them from damage by other parts.

フラツター特性の良好なものである。 The present invention is constructed as described above, and a coil spring is inserted between the upper washer and the lower washer between the upper surface of the flywheel body and the lower surface of the bearing on which the capstan shaft of the flywheel body is pivotally supported. At least one protruding portion is provided on one of the upper and lower washers, and an engaging portion for allowing insertion of the protruding portion is formed on the other, so that the upper and lower washers and the coil spring are integrated. Since the coil spring is rotated at a constant angle, the coil spring does not twist, the flywheel rotates smoothly, the capstan shaft rotates evenly, and there is no play in the thrust direction of the flywheel, resulting in good wow and flutter characteristics. .
