(54) Attachment structure for engine fuel pump


(57) A cast rear case (6) is provided on a front of an engine, and defines, with a front cover (7), a housing space for a timing chain mechanism. The rear case (6) includes an extension (11) extending outwardly in a sideways direction of the engine. A pump attachment portion (12) is formed on a surface of the extension (11) at a rear of the engine. A supply pump (4) is fastened to the pump attachment portion (12) by a bolt so that the supply pump (4) is driven by a crankshaft via chains of the timing chain mechanism. This provides secure support of the fuel pump (4) to be driven by a rotational force of the engine as a power source, without use of a dedicated bracket, and without lowering latitude in layout of other devices or accessories attached to a side of the engine.
