Abstract (en)
A three-dimensional cam device having a cam follower adapted to rock in a direction inclined with respect to the direction of displacement of a cam surface of a three-dimensional cam. The sliding surface of the cam follower is in the form of a convex of an arcuate cross-section when viewed from the axial direction of a rocker shaft, and at least a pad of the cam surface is formed with a concave surface such that the axially central portion of a three-dimensional cam is curved inward from other portions. <IMAGE>
