ABSTRACT:
A transmission with a simple structure and mechanism, light-weight and compact is realized. In the transmission, a first rotation shaft coaxially fixed to a first turning transmission wheel and a second rotation shaft coaxially fixed to a second turning transmission wheel are arranged in parallel with each other. A support shaft is arranged to extend between the first turning transmission wheel and the second turning transmission wheel. An intermediary transfer wheel is provided on the support shaft rotatably and movably along the longitudinal direction of the support shaft. The intermediary transfer wheel contacts with a side peripheral surface of the first turning transmission wheel and the side peripheral surface of the second turning transmission wheel and moves longitudinally along the support shaft while maintaining the contact.
