Provided is a belt-type continuously variable transmission which may prevent a servo spool from sliding even when a movable sheave slides due to reduced pressure in a hydraulic cylinder. A hydraulic servo mechanism (280) includes a servo spool (283) and a feedback spool (84), and contact members (278F, 278R) coming into contact with the feedback spool (84) between a hydraulic cylinder (270) and the feedback spool (84). The present invention also comprises a spool position maintaining unit that makes it possible for the contact members (278F, 278R) to slide in relation to a movable side cylinder case (271) when pressure in the hydraulic cylinder (270) is lower than a predetermined value. |
