ABSTRACT:
A bearing structure for a cam shaft has a first journal-receiving cavity of a semi-circular cross section provided in an upper face of a cylinder head, and a second journal-receiving cavity of a semi-circular section provided in a lower face of a bearing cap. The bearing cap is mounted on the cylinder head with the two faces joining together. A groove is provided in at least one of the two joining faces to extend across that face and to communicate at one end thereof with the internal space of the cylinder head so as to collect or intercept oil leaking out through a clearance left between the two adjacent faces.
