PURPOSE:To obtain sliding property with small resistance which is stable for a long time so as to eliminate necessity of size adjustment for application of a film, by forming the film consisting of a fluorine included polymer at least at one of the sliding surface of a carriage or the surface of the counterpart axis. CONSTITUTION:With regard to a carriage 3 which reciprocates along a main axis 3 and an auxiliary axis 2, a film consisting of a fluorine included polymer is formed, at least at one of axis 1 and 2 or the sliding surface 4 of the carriage 3. It is desirable that this film consisting of a fluorine included polymer is made of a polyfluoroalkyl polymer or a fluoropolyether polymer and includes a functional group having a high affinity to bearing material. These are dissolved in a solvent and applied and after that, the solvent is evaporated and the thickness of the film is made less than approximate 8mum. Accordingly, it is unnecessary to specially adjust the size for application, and sliding resistance is made small and sliding property can be stable for a long time.
