<p>In this crankshaft support structure in an internal combustion engine, it is possible to increase the compactness of an oil pump while increasing the compactness of the internal combustion engine using a bush bearing. In the support structure of a crankshaft supported by a left/right split crank case (25) that sandwiches the crankshaft (41) and is joined from both sides in the axial direction of the crankshaft (41), whereas the two crank bearings that support both ends of the crankshaft (41) are bush bearings (111), the bearing of a large end (42A) is a roller bearing (112).</p> |
