Abstract
A cylinder coupling structure of a compact air compressor includes a block, a tubular-shaped cylinder assembled to the block, a valve cover which covers the valve assembly, and at least one pressurized bolt which assembles the valve cover and the block. A piston is reciprocated inside the cylinder. A stator is assembled to the block, a rotator is located to relatively rotate as to the stator, and a crank axis is assembled to the rotator to integrally rotate with the rotator to be axially supported in the block and to be rotatable. A connecting rod, each of both ends thereof is connected to the crank axis and the piston, respectively.
