<p>A chain guide (1) improves bending rigidity while satisfying requirements for compactness and weight reduction of an engine and restricting cost increases. The chain guide (1) includes a guide body (2) having an engaging protrusion (25) capable of engaging with a long engaging hole (51) formed in an engine block in a longitudinally slidable manner and a shoe (3) fixed over the guide body (2) and having a chain sliding surface (30). In this case, an upward support of the engaging protrusion (25) of the guide body (2) in the engaging hole (51) of the engine block results in an increase in the bending rigidity of the whole chain guide (1). Moreover, the engaging protrusion (25) of the guide body (2) is only inserted into the engaging hole (51) of the engine block. This does not cause an increase in size and weight, and causes only a slight change of a mold, leading to less cost increases.</p> |
