PROBLEM TO BE SOLVED: To prevent rusting of a bolt for fixing a cylinder head of an air compressor.SOLUTION: A compressor includes a cylinder compressing air by making a piston driven by a motor reciprocate inside, a cylinder head mounted on the cylinder by a bolt, an air valve specifying the direction of airflow in the cylinder, and a head packing disposed between the cylinder head and the air valve for sealing the air in the cylinder. A communication passage communicated with the atmospheric air, is formed on a bolt fixing hole formed on the cylinder head, at a position almost same as the head packing in the horizontal direction or above the head packing to communicate the packing with the atmospheric air. |
