<p>A continuously driving transmission requiring no separate actuator for changing change gear ratios, capable of shifting gears in response to a load, capable of reducing a size and a cost, and capable of taking large change gear ratios, comprising a means for transmitting a rotation to a rocker arm (4) through a connecting rod (18) to reciprocatingly move the rocker arm (4) and changing the stroke of the rocker arm so as to drive an output shaft (2) in one direction even if the rocker arm (4) is driven to any side of the reciprocating motion, wherein the stroke of the reciprocating motion is changed by forming an input side rotating body (13) so as to drive an output side rotating body (14) through an energizing spring (12), and when the load is increased, a crankshaft lever is rotated clockwise by a cam groove (13d) to shorten a distance between Q and S, whereby the torque and rotational speed of the output shaft can be varied by changing the stroke.</p> |
