摘要： In a belt type continuously variable transmission in which a pulley shaft (SP) is supported by bearings (31, 32) provided at two positions that are apart from each other in an axial direction of the pulley shaft (SP) and a supply oil passage for supplying hydraulic fluid to a pulley hydraulic chamber (40A, 40B) includes a radial direction oil passage (SPB) that is formed in the pulley shaft (SP,), the radial direction oil passage (SPB) is formed on an outside of an area between the above-mentioned two positions. Also, one of the bearings (32) is provided near the radial direction oil passage (SPB) and on an outer surface side of a cylinder member (70) whose inner surface side forms the pulley hydraulic chamber (40B) for a movable sheave (38) that is fixed to the pulley shaft (SP). With this structure, concentration of stress on the radial direction oil passage can be avoided, and therefore strength of the pulley shaft can be secured.
