    摘要： A ringed coolant water passage 16 formed to surround a plurality of cylinders #1-#4 is provided. Two partitioning members having a larger thermal expansion coefficient as compared to that of a cylinder block 10, and separating the ringed coolant water passage 16 into first passage 22 and second passage 24 is provided. The first passage 22 exists mainly at one side of a longitudinal bore center plane which extends along the longitudinal direction of the cylinder block 10 while the second passage 24 exists mainly at the other side. An inlet which communicates with the first passage and an outlet which communicates with the second passage are provided. A cylinder head including a coolant water passage which opens to both of the first passage 22 and the second passage 24 is attached to the cylinder block 10. The cylinder block 10 and the partitioning members 12, 14 are formed so that stress acting between both of them in a condition where the internal combustion engine is warmed up does not reach to a breaking stress of the partitioning members 12, 14.

    摘要： A camshaft support structure of an internal combustion engine (10) includes a camshaft (26, 30) that drives an intake valve (18) or an exhaust valve (20); a head cover (34) that houses the camshaft (26, 30); an upper bearing portion (42) which is provided on the head cover (34) and supports the camshaft (26, 30); a lower bearing portion (54) which is attached to the head cover (34) and makes a pair with the upper bearing portion (42) to retain the camshaft (26,30); a rocker arm (22, 24) that transmits driving force from the camshaft (26, 30) to the intake valve (18) or the exhaust valve (20); and a rocker arm support portion (56) that inhibits the rocker arm (22, 24) from falling out of position by being provided near and directly above the rocker arm (22, 24).
