A variable valve device includes a pair of cam housings separated from each other in a predetermined direction, a pair of rocker shafts supported by the pair of cam housings, a plurality of rocker arms supported by the pair of rocker shafts in a swingable manner, a switching mechanism that couples and separates intake arms, and an upper housing on the pair of cam housings. The upper housing is formed with a first injection hole for supplying lubrication oil to the switching mechanism and a second injection hole for supplying lubrication oil to the rocker arms. A passage length from a lubrication groove around a camshaft to the second injection hole is larger than a passage length from the lubrication groove to the first injection hole.
