がある。(Prior art) Conventionally, as a drive for the camshaft in a V-type engine,
A device equipped with a gear reduction gear is known, for example, as seen in Japanese Patent Application Laid-Open No. 56-83507. This gear reduction device uses a reduction gear to perform a first stage of deceleration of the rotation of the crankshaft on both banks, and from this reduction gear, a timing chain performs a second stage of deceleration of the camboot of each bank. It is designed to be driven. By employing the speed reduction device described above, the diameter of the cam pulley can be reduced, which is advantageous in downsizing the engine, but there is a problem in that the noise caused by the meshing of the gears increases.

するようにしている。Therefore, as shown in upper L', it is necessary to drive the camshaft by rotation of the crankshaft, and also to drive the oil pump. Generally, this oil pump is driven by providing a gear for taking out driving force on the crankshaft, and connecting this gear and the driving gear of the oil pump with a bell 1 to a member.

害となるものである。However, for belt members such as those mentioned above, it is necessary to install a tensioner mechanism to adjust the tension in order to obtain reliable transmission, but the crankshaft and oil pump are close to each other, The belt member is short, making it difficult to install the tensioner mechanism. Generally speaking, since a gear for driving the oil pump is provided on the crankshaft separately from a gear for driving the camshaft, the overall length of this crankshaft becomes long, which becomes an obstacle when trying to shorten the overall length of the engine. It is what it is.

A timing belt member drive gear is provided, and a belt member passed between the rotational force extraction gear and the reduction gear transmits the rotational force of the crankshaft to the reduction gear, and the belt member is connected to the rotational force extraction gear of the crankshaft. The feature is that the hook is also passed to the oil pump drive gear provided directly below, so that the oil pump is driven at the same time.
