Abstract
An internal combustion engine includes a crankshaft that is rotatably supported on a crankcase via a pair of bearings and has a crank housed in a crank chamber, a to-be-detected body that is housed in the crank chamber and is supported on the crankshaft, and a detection sensor that is made to face a trajectory of the to-be-detected body and detects movement of the to-be-detected body to generate a pulse signal. The to-be-detected body is disposed on an inner side of the bearing. Thus, an internal combustion engine is provided that enables a crank angle to be detected in a state in which vibration and flexure occurring in a crankshaft are suppressed.
