keyway 32 and in the provision of a radial slit 37 in each of the outer body member 31 and the inner body member 36 the spiral type one way clutching mechanism shown in the spiral type one way clutch assembly of fig7 may be that of fig1 or 2 or by suitable modification for interconnection that of fig5 or 6 in other words since outer annular member 11 in fig5 and 6 are radially split the resiliency of such member will hold it within the clutching mechanism the inner cylindrical surface of the inner body member 16 36 is modified to provide an inner right conical surface 50 the outer body member 11 36 is keyed to the axially stationary member 51 by key 52 if the clutching mechanism is that of fig5 or 6 the outer body members 11 31 are free to overrun but can be actuated to engage in the manner as previously described two end plates 53 and circlips 54 prevent axial movement of the clutching mechanism shaft 57 is provided with an axial ball spline 55 through which axially movable member 56 having a conical outer surface 56a is attached to the shaft 57 the cone angle u03b5.
