<p>A compressor characterized in that the connection part between a chamfered part on the piston top side and a piston cylindrical surface and the connection part between a chamfered part or a recess on the cylinder bore top side and a cylinder bore cylindrical surface are set in such a positional relation that they don't slidingly contact with each other in the axial and/or circumferential directions of a cylinder bore. Consequently, a piston coating can be prevented at a low cost from being peeled off without increasing the size of the compressor, whereby the durability of the compressor can be enhanced.</p> |
