A port cover is removably attached to a compressor to protect a port of the compressor. The port cover is integrally made of elastomer and has a cap member adapted to close the port, a cover member coupled to the cap member and adapted to cover a pipe fixing portion of the compressor, and a handle extending from the cap member. The cover member has a cylindrical portion faced to a side surface of the pipe fixing portion. The cylindrical portion has a specific portion extending from a first end of the cylindrical portion opposite to the compressor towards a second end opposite to the first end. The specific portion allows the first end of the cylindrical portion to be increased in diameter.
