Oil filter mounting structure in internal combustion engine
First Claim
1. An oil filter mounting structure in an internal combustion engine in which the outside a crankcase in the direction of a crankshaft is covered by a case cover, comprising:
- a spacer interposed between the crankcase and the case cover, the spacer being formed with a lubrication system,the spacer being provided with an oil filter mounting surface which is flush with a first mating surface with respect to the crankcase, and a part of the crankcase to which the oil filter mounting surface of the spacer faces is formed with a recess opening on top,wherein the oil filter is mounted on the oil filter mounting surface and extends into the recess of the crankcase.

Abstract
An oil filter mounting structure in an internal combustion engine in which the outside a crankcase in the direction of a crankshaft is covered by a case cover. A spacer is interposed between the crankcase and the case cover. The spacer is formed with a lubrication system. An oil filter is mounted to an oil filter mounting surface of the spacer which is flush with a mating surface with respect to the crankcase. A part of the crankcase to which the oil filter mounting surface of the spacer faces is formed with a recess opening on top to which the oil filter is mounted. The resulting configuration provides an oil filter mounting structure in which an oil filter is reliably protected from stones. Further, oil channels are shortened to achieve a compact light-weight internal combustion engine.
