Abstract

In a horizontal opposed type internal combustion engine, to enable rigid support of a middle journal of a crank shaft through rational utilization of first and second case halves constituting a crankcase, and to thereby contribute to a simplification in structure and a reduction in weight. In a horizontal opposed type internal combustion engine in which a crankcase 6 is split at a plane P containing the axis line A of a crank shaft 1 into first and second case halves 6L, 6R connected with first and second cylinder blocks 7L, 7R, the first and second case halves 6L, 6R
are provided integrally with first and second journal supporting walls ~13Lm, 13Rm for supporting a middle journal 3m of the crank shaft 1, the first and second journal supporting walls 13Lm, 13Rm fronting on cylinder bores 10Lr, 10Rf of the first and second cylinder blocks 7L, 7R, and the first and second journal supporting walls are coupled by a plurality of first bolts 19L inserted from the side of the cylinder bore 10Lr of the first cylinder block 7L and disposed on both sides of and in proximity to the middle journal 3m.
