Abstract
An internal combustion engine includes a crankshaft that has a journal linked to a bearing and is rotatably supported on the crankcase, a power transmission gear fixed to an extremity of the crankshaft that has a smaller diameter than a diameter of the journal and projects outward of the crankcase, a to-be-detected body that is fixed on an outer periphery of a collar member disposed between the bearing and the power transmission gear and is relatively non-rotatably 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. This provides a structure for disposing a to-be-detected body that enables any increase in the dimensions of an internal combustion engine to be avoided.
