Abstract: An accessory support structure for a vehicle engine includes a pair of accessory-side supports provided on the engine accessory, and a pair of engine-side supports provided on the engine body. The engine-side supports each have a shaft hole into which a bolt is inserted, a slot closer to the engine body than the shaft hole is, and extending substantially horizontally, and an intermediate portion interposed between the shaft hole and the slot to restrict movement of the bolt. The engine-side supports each remove a restriction imposed by the intermediate portion and guide the bolt from the shaft hole to the slot if an external force acting on the alternator toward the engine body exceeds a predetermined threshold.

Abstract: An engine oil supply apparatus includes: a cylinder block; a shaft supporting member which bears a crank journal of a crank shaft in cooperation with a journal supporting wall section; and a nozzle which injects oil to a piston. The cylinder block includes a first oil supply path which extends in a cylinder bank direction at a position of one side section of the cylinder in a width direction that is perpendicular to the cylinder bank direction, a branch oil path which branches from the first oil supply path at a position of the journal supporting wall section and which supplies oil to a crank bearing section by which the crank journal is borne, and a second oil supply path which extends in the cylinder bank direction at a position further outward than the first oil supply path in the width direction and which supplies oil to the nozzle.
