FIELD: watch industry. ^ SUBSTANCE: movable item which is described in the invention has specific resiliency in its center to provide its shift without changes in intra-center distance. Movable item intended for introducing it into contact with movable or motionless member has boss rotating around its axis which has to be central axis of rotation of movable item, support or transmission wheel which has transmission or working area intended for introduction with contact of movable or motionless member. Resilient area is placed between boss and transmission area being deformed under action of side pressure applied to transmission wheel to shift working area in such a manner that axis of rotation of transmission area would coincide with central axis of rotation of movable item. ^ EFFECT: improved efficiency. ^ 9 cl, 9 dwg |
