PURPOSE:To remove the oil contained in the discharged gas by forming a honeycomb material by laminating thermoplastic resin and covering a piston rod with said honeycomb structure. CONSTITUTION:The slidable part of the piston rod 1 of a compressor is covered with a honeycomb material 2. The honveycomb material 2 is formed by laminat ing at least two layers of the thermoplastic resin such as polyalkylene terephthalate, and possesses the expandable structure due to a number of in dependent air chambers formed. Therefore, oil mists are liquefied, and the honeycomb itself discharges oil portion, and the oil portion contained in the discharged gas of the compressor can be effectively removed.
