Abstract

PURPOSE:To easily enable the fitness of a movable flange to an unmovable frange by determining the phase shift between inner and outer pawls for at least one of the movable and unmovable flanges, and advancing a shifting cylindrical member. CONSTITUTION:The angular phase between inner and outer pawls 8a, 8b is shifted by 90 deg.. For the engagement of a clutch, turning of a control lever 11 advances a shifting cyrindrical member 9 in the direction of an unmovable flange 6, then springs 14a, 14b pushes inner and outer movable flanges 2a, 2b in the direction of the unmovable flange 6. In this condition, the protruded and recessed portions of an inner pawl 5a and the inner pawl 8a are corresponding to each other, while those of an outer pawl 5b and the outer pawl 8b are not corresponding, and, therefore, they can not be fitted. The protruded tip ends of the outer pawls 5b, 8b are brought in contact with each other, whereby the outer ring 14b shrinks, while the inner movable flange 2a advances further so that the inner pwals 5a, 8a are fitted to each other.

It is now assumed that the non-moving flange 6 and the moving flange 2 are in a relative positional relationship as shown by S in FIG. 7. In this state, the inner claws 5a and 8a have their protrusions and recesses aligned (that is, the protrusions are not shaped like each other), so they are ready to fit together, but the outer claws 5b and 8b have their protrusions and recesses aligned. Since they do not match, they cannot be mated. Therefore, the outer moving flange 2b
The tips of the convex portions of the outer claws 5b and sb collide with each other and cannot move forward any further, and the outer spring 14b contracts. On the other hand, the circularly movable flange 2a continues to move forward, and the inner claws fit into each other.

Similarly, when the relative relationship between the movable and non-movable flanges 2.6 is as in the U state shown in FIG. When the movable flange 2 is driven, the convex portions of the outer claws come into contact with each other and the non-movable flange 6 rotates, as shown by V in the figure. Like this V
When the state is reached, the inner flange 2a is pushed forward by the spring 14a and the inner end 19a of the cam I7, and the inner claws 5a,
5b is also fitted.

In the embodiments described so far, the angles of the inner and outer claws are in the same phase for the moving flange 2 and 90 degrees apart for the non-moving flange 6, but the invention is not limited to this. In short, regardless of the relative angular positions of the moving and non-moving flanges,
It is only necessary that the phases of the inner and outer claws of at least one of the movable flange and the non-movable flange are shifted so that the convex portion and the recessed portion of at least one of the inner and outer claws match. For example, the same effect can be obtained by shifting the angles of the inner and outer claws by 45 degrees for the moving flange and 45 degrees for the non-moving flange on the opposite side.
