<P>PROBLEM TO BE SOLVED: To provide a continuously variable transmission that suppresses a slide of a belt. <P>SOLUTION: The continuously variable transmission 3 comprises: an input-side primary pulley 10 which changes a groove width by hydraulic pressure; a secondary pulley 11 which changes the groove width by the hydraulic pressure; a variator 5 having a power transmission member 12 wound to the primary pulley 10 and the secondary pulley 11; a first hydraulic control means 6 which feeds and discharges oil to/from the primary pulley 10 or the secondary pulley 11; a first clutch mechanism 4 which transmits the power of a drive source 1 to drive wheels by being fastened, and blocks the transmission of the power of the drive source 1 to the drive wheels by being released; and a second hydraulic control means 7 into which a portion of the oil which is fed and discharged by the first hydraulic control means 6 is introduced, and in which a fastening force of the first clutch mechanism 4 is reduced as pressure generated by the introduced oil becomes low. <P>COPYRIGHT: (C)2013,JPO&INPIT |
