PURPOSE:To constitute an oil chamber so easily as well as to aim at improvements in lubricating capacity ever so better, by constituting the oil chamber with an empty space part being surrounded by a cover of a base body and a shaft extended from the base body to the cover side. CONSTITUTION:Inside a crankcase 40 or a base body, a crankshaft 41 or a shaft is rotatably supported via symmetrical journal bearings 42 and 43. And, at both sides of the crankcase 40, there are provided covers 59 and 60 through which a clutch 55 and an AC generator 58 are covered. As in the above-mentioned, an oil chamber 73 is constituted of an empty space part being surrounded by one end part of the crankshaft 41, an inner end face of the cover 60 and a projecting peripheral wall 74 formed in the center of the inner end face of the cover 60. And, an end part at the downstream side of a feed passage 63 of the cover 60 is opened to the inside of the oil chamber 73. With this constitution, the oil chamber 73 can be easily constituted, thus lubricating capacity is improvable. |
