<p>A motion converting mechanism wherein two sets of one-way clutch mechanism are added to a mechanism for converting a reciprocating straight-line motion into a rotary motion through a combination rack and pinion gear. The two sets of one-way clutch mechanisms include one that engages during the forward motion of the rack and the other that engages during the backward motion of the rack, both of which rotating an output shaft in the same direction when they engage. With this arrangement, the motion converting mechanism according to the present invention can rotate the output shaft in the same direction during the forward motion and the backward motion of the rack, thereby improving efficiency in converting the reciprocating motion into the rotary motion as compared with the convention one. Thus, various revolving tools utilizing this motion converting mechanism can be provided. One of these revolving tools is a ratchet type socket wrench, in which an arm is reciprocated, so that the output shaft can be rotated in the same direction during both the forward and backward motions. Another one is a revolving tool such as a screw driver, in which a grip is grasped or released, so that the output shaft can be rotated in the same direction during the both motions.</p> |
