ABSTRACT:
A torque-applying hand tool includes a stepless mechanism for turning an object in a desired direction through an unlimited range by swinging the handle thereof. The stepless mechanism comprises a polygonal shaft and rollers each being placed in touch with each side of the polygon shaft. Each roller is selectively forced to one end or the other of each side so that the polygon shaft may be turned in one direction when the tool handle is turned. At one end of the polygon shaft is formed a socket or box shaft to engage with the object to be turned. In such a tool, the stepless mechanism can be made compact with an unlimited turning range of the object.
