Abstract
The present invention relates to a variable valve operating device and makes it possible to inhibit friction during driving force transmission and provide high durability through the use of a compact configuration. A first roller, which comes into contact with a drive cam surfaceof a camshaft, has a larger diameter than a second roller, which comes into contact with a slide surfaceof a swing member. A coupling shaftcouples the first rollerto the second rollerso that the rollerscan rotate independently. The slide surfaceis curved toward the drive cam surface
