| 摘要 |
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 170, which comes into contact with a drive cam surface 124 of a camshaft 120, has a larger diameter than a second roller 172, which comes into contact with a slide surface 156 of a swing member 150. A coupling shaft 174 couples the first roller 170 to the second roller 172 so that the rollers 170, 172 can rotate independently. The slide surface 156 is curved toward the drive cam surface 124.
