Abstract
A camshaft support structure for an internal combustion engine includes a cylinder head, a camshaft, a plurality of bearings, an auxiliary machine drive cam, an auxiliary machine, and a pulsar plate. The plurality of bearings include a terminal bearing supporting the camshaft to be rotatable with respect to the cylinder head about a rotational axis. The auxiliary machine has a plunger provided to be moved forward and backward by the auxiliary machine drive cam. The pulsar plate projects from the camshaft in a radial direction of the camshaft and is provided on an opposite side of the auxiliary machine drive cam with respect to the terminal bearing. The pulsar plate has a second surface facing the terminal bearing in the axial direction. Each of the first surface and the second surface is provided to slidably contact the terminal bearing.
