Oil is supplied to a journal surface of the camshaft and a bearing supporting the camshaft journal surface through an axial oil passage formed in the camshaft. The bearing is defined by a cam cap and a bearing main body. An oil collecting recess is defined between cam cap and the bearing main body. An auxiliary delivery passage extends from the oil collecting recess to a sidewall of the bearing that is located adjacent to the valve lifter. A guide wall is formed in the sidewall to lead oil from an opening of the auxiliary delivery passage to a part of the valve lifter that generates a striking noise in the absence of buffering oil.
