Patent ID: 8701837

Claim:
A chain-type driving force transmitting apparatus comprising: a case formed by joining a front case and a rear case to thereby form a lower space accumulating therein lubricating oil; an input shaft rotatably supported by the case; an output shaft arranged in parallel with the input shaft and rotatably supported by the case; a chain wound around the input shaft and the output shaft, the chain configured to transmit driving force inputted from the input shaft to the output shaft and to lift up the lubricating oil accumulated in the lower space of the case; a separator positioned adjacent to the chain and extending perpendicularly to an axial direction of the input and output shafts, the separator being positioned in the front case and extending from a bottom surface of the case to a level higher than the output shaft to thereby be positioned over the output shaft such that a top end surface of the separator is positioned at a level lower than the input shaft, whereby the lower space of the case is divided in a transverse direction thereof into a first chamber in which the chain is provided and a second chamber; and an inclined portion provided at an upper end of the separator and inclining toward the chain so as to receive the lubricating oil lifted up by the chain, wherein the lubricating oil received by an upwardly facing surface of the inclined portion flows into the second chamber; and wherein the second chamber houses a strainer which collects the lubricating oil accumulated in the lower space.
