摘要： An overhead-valve internal combustion engine with a breather chamber arranged below a camshaft housing chamber for housing the camshaft and formed between a cylinder head and a cylinder block. A driving force transmission chamber is formed between a cylinder and a crankcase. Thus, the discharge of oil from the breather chamber is performed smoothly so as to enhance the vapor-liquid separation performance. A breather inlet passage has an upper end thereof in communication with an inside of a camshaft housing chamber and a lower end thereof in communication with a breather chamber at a position corresponding to a mating face between a cylinder block and a crankcase is formed in the cylinder block such that the breather inlet passage extends vertically. An oil discharge hole is in communication with a lower portion of the inside of the breather chamber and is formed in the crankcase.

摘要： A transmission assembly includes a shift drum operable to rotate in first and second directions. The shift drum includes a common speed change position, where both a fastest forward gear and a reverse gear are capable of becoming engaged, in such a manner that a reverse stopper arm fits at a first end of a reverse cam groove formed on the shift drum. When the shift drum is rotated in the second rotation direction, opposite to the first direction, from a state where the reverse gear is engaged, the reverse stopper arm surmounts the outer periphery of the shift drum from the first end of the reverse cam groove, without requiring the application of an external force thereto, so as to become detached and to move towards a second end of the reverse cam groove.

摘要： A vehicular transmission for an internal combustion engine includes lead grooves disposed on an outer periphery of a shift drum having communication portions connecting a pair of gear train establishment portions extending circumferentially along the shift drum. The communication portions include half neutral portions formed at a center thereof, extending circumferentially along the shift drum. The resulting configuration suppresses an engagement noise to a minimum during changing of a gear position through a sliding motion of a shifter.
