等の問題がある。<Problem to be solved by the invention> Conventionally, this type of control mechanism consisting of a control plate and a hub flange has been known to generate so-called transmission rattle noise (when the transmission is placed in a neutral state, noise caused by uneven rotation of the engine, etc.) To reduce rotational vibrations that are the source of muffled noise in the drive system, such as the hammering sound caused when the tooth surfaces of two meshing gears come into contact with each other, to increase hysteresis in the operating state, or to determine the starting point of the control board's action. However, in the conventional control mechanism using a control plate compatible with the hub flange, the friction surface of the control plate is not sufficient and the hysteresis of the second stage cannot be made sufficiently large. The contact surface of the engagement tongue is small, so it is necessary to use multiple tongues (Kokoku Sho 52-53889), or the thickness of the control plate or tongue is thicker than necessary for friction control. There are problems such as the need to do so.

The wall thickness of the hub flange can be made thinner than before, and the outer diameter can also be made smaller. As a result, the moment of inertia of the clutch plate can be reduced, and the periodic characteristics of the periodic mechanism of the transmission can be improved. By using it in combination with the example control plates, it becomes easy to incorporate multiple control plates into the clutch plate (at least one each on both sides of the hub flange), and the radial window width is reduced to the minimum necessary for accommodating the springs. Since it can be suppressed to a limit, it is also possible to make the friction surface wider radially inward of the window portion, which can also contribute to improving the hysteresis width of the control mechanism.

A friction device disposed within the window and capable of engaging with the other, larger notch window in the circumferential direction of the hub flange or clutch plate, for damping rotational vibration in the clutch operating range, and a control means for determining the start of this friction action. A central cylindrical portion, a hub flange formed radially outward from the cylindrical portion, and the hub flange for use in a clutch plate of a type in which the portion of the hub flange can be engaged with any of the notched windows of the hub flange. a stopper pin receiving and engaging recess distributed on the outer periphery of the recess, at least one notch window for accommodating the spring disposed circumferentially with a common side edge of the recess, and a radial radius of the notch window. In the clutch hub having a friction surface on the center side, the cutout window has a recessed portion facing the center side half portion of the side edge formed in parallel to the radial outward direction and extending the window in the circumferential direction. A clutch hub characterized in that a bent piece having a radial length corresponding to the recess of the arm portion of the control means can be accommodated in the recess in a loose manner in the circumferential direction.
