What is claimed is: 1. An oil pump for a scroll compressor, comprising: a driving shaft having an oil passage formed therein; a gear driving unit coupled to the driving shaft; a pump body having a driving shaft insertion groove formed at an upper side thereof; a friction reducing member inserted in and seated on a bottom of the driving shaft insertion groove so as to reduce friction between the driving shaft and pump body; a gear unit coupled to the pump body so as to rotate together with the driving shaft; and a pump cover coupled to the pump body and having an intake that draws in oil. 2. The oil pump of claim 1, further comprising: a filter member that filters foreign elements from the oil drawn in through the intake, said filter member being positioned on a lower side of the pump cover. 3. The oil pump of claim 2, wherein the filter member has a plurality of assemblage holes through which an assemblage member penetrates, and a distance between the holes are different from each other. 4. The oil pump of claim 1, wherein the friction reducing member has a drive unit penetrating hole through which the drive unit penetrates. 5. The oil pump of claim 1, wherein the friction reducing member has a protruding fixing unit that fixes the fiction reducing member on the pump body, and wherein the pump body has a fixing hole into which the protruding fixing unit is inserted. 6. The oil pump of claim 1, wherein an outer diameter of the gear driving unit is smaller than that of the driving shaft. 7. The oil pump of claim 1, wherein a driving surface for rotating of the gear unit is formed on the gear driving unit. 8. The oil pump of claim 1, further comprising: a guide groove for smoothly drawing in oil formed on a circumferential surface of the gear driving unit. 9. The oil pump of claim 1, wherein the oil passage includes a first oil passage, and a second oil passage formed perpendicular to and connected to the first oil passage. 10. The oil pump of claim 9, wherein the pump cover has an outlet for discharging the oil, drawn in through the intake, to the gear unit, wherein the outlet is positioned at a height corresponding to the first oil passage when the gear driving unit is mounted on the pump cover. 11. The oil pump of claim 1, wherein the gear unit includes an outer gear having gear teeth formed on an inner circumferential surface thereof, and an inner gear having gear teeth formed on an outer circumferential surface thereof and coupled to the outer gear. 12. The oil pump of claim 11, wherein a plurality of chambers for accommodating the oil are formed between the inner gear and the outer gear. 13. An oil pump for a scroll compressor, comprising: a pump body; a driving shaft coupled to the pump body; a gear unit installed on the pump body so as to rotate together with the driving shaft; a friction reducing member that reduces friction between the driving shaft and the pump body; a pump cover coupled to the pump body, wherein the pump cover covers the gear unit and includes an intake; and a filter member coupled to the pump cover and covering the intake so as to filter foreign elements from oil flowing therethrough. 14. The oil pump of claim 13, wherein the pump cover and filter member are coupled on the pump body by a single assembly member. 15. The oil pump of claim 13, further comprising: a fixing unit formed on the friction reducing member, and fixing holes formed on the pump body so as to receive the fixing unit therein. 16. The oil pump of claim 13, wherein a driving shaft insertion groove is formed on the pump body and a gear insertion groove that receives the gear unit is formed on the pump body, and a driving shaft penetrating hole is formed between the driving shaft insertion groove and the gear insertion groove. 17. The oil pump of claim 13, wherein a gear driving unit coupled to the gear unit is formed integrally on the driving shaft, and wherein a diameter of the gear driving unit is less than a diameter of the driving shaft. 18. The oil pump of claim 13, wherein the gear unit includes an outer gear having gear teeth formed on an inner circumferential surface thereof, and an inner gear having gear teeth formed on an outer circumferential surface thereof, wherein the inner gear is inserted into the outer gear. 19. The oil pump of claim 13, wherein the driving shaft includes a first oil passage that draws in oil and a second oil passage connected to the first oil passage that transfers oil drawn in through the first oil passage. 20. An oil pump for a scroll compressor, comprising: a pump body; a driving shaft coupled to the pump body, and having a gear driving unit including a horizontal first oil passage that draws in oil and a second oil passage coupled to the first oil passage; a friction reducing member that reduces friction between the driving shaft and pump body; a gear unit installed on the pump body so as to rotate together with the driving shaft; and a pump cover coupled to the pump body and having an intake that draws in oil and an outlet that discharges oil, wherein at least a portion of the gear driving unit is inserted into the pump cover such that when the horizontal first oil passage is aligned with the outlet, oil flows from the outlet into the horizontal first oil passage.
