Abstract
An engine unit for a vehicle comprises an engine case in which a crankshaft and a counter shaft are rotatably supported and an oil pump is provided so that rotation of the crankshaft is transmitted to the counter shaft. The counter shaft serves as a driving shaft of the oil pump arranged to be coaxial with the counter shaft. The oil pump has a pump case, which is provided with a tubular engaging member concentrically surrounding the counter shaft to extend in an axial direction thereof and with a discharge passage extending so as to be apart from the counter shaft in the axial direction thereof. The tubular engaging member is fitted into a fitting hole for a counter shaft bearing and the discharge passage having an end portion fitted into an oil supply port formed in the engine case.
