<P>PROBLEM TO BE SOLVED: To supply a lubricant for a long period of time to both a threaded shaft and a guide rail of a uniaxial actuator in which both side faces of the guide rail, a slider and an upper side of the threaded shaft are overlaid with a cover. <P>SOLUTION: When moving the slider 3, a grease nipple 83 provided in a moving-direction end of the slider 3 is fitted into a nipple insertion port 52a provided in a guide rail 1. As a result, a greasing path 81 of a greasing block 8 fixed on an upper surface of the slider 3 and a greasing path 52b of an end block 5 fixed on an upper surface of the guide rail 1are made to communicate with each other. A lubricant is supplied from greasing piping coupled to the grease nipple 53 into the slider 3 via both the communicating greasing paths 81, 52b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
