The present invention provides an anti-rotation structure for a balance chamber snap ring of a belt type continuously variable transmission having a balance chamber that balances a centrifugal oil pressure generated in an oil pressure chamber formed on a movable sheave back surface. A projecting portion, which comes into contact with an end portion of the balance chamber snap ring when the balance chamber snap ring rotates independently within a ring groove about a secondary shaft, thereby restricting independent rotation of the balance chamber snap ring, is provided on a latch portion of a cover member. As a result, independent rotation of the balance chamber snap ring can be prevented, thereby preventing the cover member and the balance chamber snap ring from becoming worn.
