The present invention relates to a driving force transmission system, which comprises a motor; a motion conversion unit converting the rotary power of the motor into a linear reciprocating motion; multiple link assemblies in which multiple link members are continuously connected in an X-shape in an elastic manner, one side is hinged and fixed to a hinge unit, and the terminal end of one side is connected to the motion conversion unit for a linear reciprocating motion so that the other side reciprocates along the longitudinal direction; sliding bars connected to the other side of each link assembly; a guide unit guiding each sliding bar to do a linear reciprocating motion; an elastic member installed to provide an elastic force to the sliding bars so that each sliding bar is restored to a linear motion direction; rack members prepared on each end of each sliding bar; gear members geared with each rack member, fixed to rotate with a third rotary shaft, and rotating the third rotary shaft in one direction with one direction bearing; and a rotary force transmitting unit delivering the rotary force of the third rotary shaft to a rotation target object. According to the present invention, the rotary force supplied from the motor is stably delivered to a rotation target object. |
