To provide a highly reliable axial force generating device by a simple constitution and to provide a traction transmission using it.
This axial force generating mechanism 10 comprises a centrifugal force generating mechanism, a converting mechanism converting the centrifugal force into the axial force, etc. The centrifugal force generating mechanism comprises a weight 11 rotating from a rotation center at a prescribed rotation radius. The converting mechanism comprises an operating member 14 fixed to an input shaft 2, a reference member 15 rotating with the input shaft 2 and displaceably supported along the input shaft 2, a positioning mechanism 20 regulating the position of the reference member 15, an arm 12 connecting the operating member 14 to the weight 11 by a pin connection, an arm 13 connecting the reference member 15 to the weight 11 by the pin connection, etc.
