ABSTRACT:
A belt type continuously variable transmission including a primary pulley; a secondary pulley; a belt which is looped over the primary pulley and the secondary pulley; a reduction gear unit that transmits torque, which has been output from an internal combustion engine and then transmitted to a secondary shaft, to a final reduction gear unit that is provided so as to be coaxial with the secondary shaft of the secondary pulley; and a damper oil chamber which is provided between the secondary shaft and an input shaft of the reduction gear unit. A thrust force generated in the reduction gear unit due to an input of a driving force is transmitted to a hydraulic fluid in a damper oil chamber, and then absorbed. Therefore, a displacement of a relative position between the primary pulley and the secondary pulley is suppressed.
