Abstract

This internal combustion engine is provided with: a transmission component (59) that is connected to a crankshaft and a camshaft and that moves along an annular path so as to transmit a rotation force from the crankshaft to the camshaft; a tensioner (66) that makes contact with the transmission component (59) in a displaceable manner along a virtual plane orthogonal to a rotation axis (Rx) and that adjusts tension of the transmission component (59); and a tensioner lifter (67) that is attached to an engine body (31) and that imparts a load to the tensioner (66) along the virtual plane orthogonal to the rotation axis (Rx). A recessed part (74), which is disposed so as to overlap with a part of the tensioner lifter (67) when viewed in the axial direction of the crankshaft (41), is disposed in an inner wall surface of the engine body (28a). Accordingly, provided is an internal combustion engine that can ensure a predetermined spring length and maintain tension more appropriately than before.
