Abstract: A vane structure for a compressor comprises: a Z-plate located in a cylinder assembly for dividing an inner space of the cylinder assembly into a plurality of compression spaces and notated by a driving unit to suck, compress, and discharge fluid; and vanes undergoing reciprocating movements by being contacted to both surfaces of the Z-plate for dividing the respective compression space into a suction area and a compression area, wherein the vane includes a vane roller which is rolling contacted to the Z-plate to reduce a friction resistance between the Z-plate and the vane, and thereby an abrasion can be minimized, a noise generation can be reduced, life spans of components can be increased, and a reliability of the compressor can be improved.
