1. An air conditioner for a vehicle comprising: an air-conditioning case having an air inflow port formed on one side thereof and a defrost vent, a face vent and floor vents respectively formed on the other side thereof for discharging the air, which is introduced through the air inflow port;a mode door having a gear shaft, which is rotatably mounted inside the air-conditioning case and has gear portions, and a thin plate member, which is slidably mounted adjacent to the vents inside the air-conditioning case and has rail portions engaging with the gear portions of the gear shaft, for controlling the degree of opening of the vents;a guide part formed on an inner face of the air-conditioning case to cover the rail portions and overlapped with the rail portions of the thin plate member; andconstant discharging means formed on the rail portions of the mode door and the guide part of the air-conditioning case so as to continuously discharge the inside air of the air-conditioning case toward one vent out of the vents;wherein the constant discharging means comprises aplurality of gear holes formed on the rail portions of the mode door so as to engage with the gear portions of the gear shaft; and cut portions formed on the guide part of the air-conditioning case by cutting a predetermined section of the guide part in a sliding direction of the thin plate member, so that air passing through the gear holes and the cut portions is continuously discharged to the one vent. 2. The air conditioner according to claim 1, wherein the face vent comprises a center vent formed at the center of the inside thereof and side vents formed at both sides of the center vent, and the cut portions are formed on the guide part formed at the side vent of the face vent. 3. The air conditioner according to claim 1, wherein a gap is formed between an inner face of the air-conditioning case and the rail portion, such that the inside air of the air-conditioning case is continuously discharged through the gap and the cut portion. 4. The air conditioner according to claim 3, wherein rail groove portions are formed on the inner face of the air-conditioning case in the sliding direction of the thin plate member so as to slidably support end portions of the rail portion, and through holes are formed in a side of the rail groove portion corresponding to the inner area of the cut portion, such that the inside air of the air-conditioning case is continuously discharged also through the through holes, the gap and the cut portions. 5. The air conditioner according to claim 1, wherein rail groove portions are formed on the inner face of the air-conditioning case in the sliding direction of the thin plate member so as to slidably support end portions of the rail portion, and the rail groove portions are formed only in an outer area of the cut portion. 6. The air conditioner according to claim 1, wherein the thin plate member comprises: an opening portion for selectively opening the face vent according to an air discharge mode; a first door portion disposed at one side of the opening portion for selectively closing the face vent; and gear holes formed on the rail portions formed on sides of the first door portion and the opening portions. 7. The air conditioner according to claim 6, wherein the gear hole formed on the side rail portion of the first door portion is larger than the gear hole formed on the side rail portion of the opening portion. 8. The air conditioner according to claim 6, wherein the thin plate member further comprises a second door portion disposed on the other side of the opening portion for selectively closing the floor vents according to the air discharge mode, the second door portion not having any gear holes in the rail portions disposed at both end portions thereof. 9. The air conditioner according to claim 1, wherein the constant discharging means further comprises: a plurality of through holes formed on the guide part of the air-conditioning case corresponding to the plurality of gear holes, such that the air passing through the gear holes and the through holes is continuously discharged to a respective vent. 10. The air conditioner according to claim 1, wherein the gear shaft, the thin plate member and the guide part are arranged in order in an air flow direction inside the air-conditioning case. 11. The air conditioner according to claim 1, wherein the face vent comprises a center vent formed at the center of the inside thereof and side vents formed at both sides of the center vent, and the rail portions are formed at both end portions of the thin plate member. 12. The air conditioner according to claim 1, wherein the face vent comprises a side vent formed at the center of the inside thereof and center vents formed at both sides of the side vent, and the rail portions are formed at both sides of the side vent.
