<P>PROBLEM TO BE SOLVED: To provide a structure in which costs can be reduced by simplifying supply means of traction oil necessary for each section. <P>SOLUTION: Traction oil functioning as lubricating oil is stored up to a position at which at least a portion of a traction section is immersed which is a rolling contact section between the axial side face of at least each disk and the circumferential surface of each of power rollers 13a and 13a in a running state in a casing. Thus, it is made unnecessary to install a nozzle for spaying traction oil to each traction section, an input rotary shaft 6a, or an supply oil passage, the processing of which in trunnions 17c and 17c is bothersome. <P>COPYRIGHT: (C)2013,JPO&INPIT |
