<P>PROBLEM TO BE SOLVED: To provide an oil supply circuit for a balance chamber of a belt type continuously variable transmission not requiring high assembly accuracy without lengthening a pulley shaft itself in regard to a belt type continuously variable transmission equipped with a balance chamber balancing a centrifugal oil pressure generated in an oil pressure chamber of a movable sheave back face. <P>SOLUTION: A rotating member 21 is connected to an outer periphery of a secondary shaft 150, and when an inner periphery of a guide member 23 having an outer periphery with an interval with a plunger 155 is fixed along with an inner periphery of the plunger 155 to an outer periphery of the rotating member 21, oil passages 155a, 211, 231 provided on the plunger 155, the rotating member 21, and the guide member 23 are communicated, and oil can be supplied to the balance chamber 156 of a movable pulley 152 back face from an oil passage 159 of the secondary shaft 150. Accordingly, it becomes unnecessary to lengthen the secondary shaft 150 itself. Moreover, since the oil passages 155a, 211, 231 are formed in a groove or hole shape, or by a notch, high assembly accuracy is not necessary. <P>COPYRIGHT: (C)2011,JPO&INPIT |
