Abstract:
In a variable valve actuation device for an internal combustion engine, a hollow boss (22b) is fitted around the outer periphery of an outer camshaft (15a) and protrudes from one side of a second cam (22a) located opposite a first cam (20) in the width direction of the second cam over a distance greater than the width of the second cam, in order to suppress misalignment of the boss.
