A variable compression ratio internal combustion engine rotates a camshaft to cause relative movement between a crankcase and a cylinder block. The camshaft has a shaft member, a cam member fixed to the shaft member, and a movable bearing member rotatable with respect to the shaft member. The cam member is rotatably housed in a cam housing hole formed in the crankcase, and the movable bearing member is rotatably housed a bearing housing hole formed in the cylinder block. |
