Abstract
An internal combustion engine including a transmission for transmitting power from a crankshaft to an output shaft through speed change, with the speed change in the transmission being performed by the driving of a speed change electric motor through a speed change drive mechanism, wherein power transmission control means for controlling the transmission of power from the crankshaft to the transmission is provided at one end of the crankshaft, and at least a part of the speed change electric motor and the speed change drive mechanism is disposed on the outside of the power transmission control means. This configuration of the internal combustion engine is reduced in size because of the layout of the speed change drive mechanism and the speed change electric motor.
