ABSTRACT:
The bidirectional differential clutch enables to transmit or cutoff both clockwise and counterwise rotation at the input side. The clutch comprises an input gear having a first cylindrical surface, an output gear having a second cylindrical surface disposed with a space to the first cylindrical surface so as to be relatively rotatable, a plurality of engaging members interposed in the space, a holding member inserted into the space, the holding member having a pocket storing the engaging members, the engaging members being for operation from a neutral position in which both cylindrical surfaces are not engaged with each other to an operational position in which both cylindrical surfaces are engaged with each other, a sub-gear producing differential velocity in correspondence to the rotation of the input gear, and the holding member being linked with the sub-gear to slide in a peripheral direction by the differential velocity to operate the engaging members to the operational position. The engaging members may be rollers or sprags.
