<P>PROBLEM TO BE SOLVED: To provide a lubricant feeding device that can feed lubricant to a surface of a raceway shaft, and can make the movement of a moving member with respect to the raceway shaft smooth in long term use. <P>SOLUTION: The lubricant feeding device is attached to the moving member assembled to the raceway shaft through a rolling body, and feeds the lubricant to the raceway shaft with the relative movement of the moving member and the raceway shaft. The lubricant feeding device includes: a lubricant reservoir having a storing space for storing the lubricant; a rotating body which rolls on the surface of the raceway shaft while being exposed to the storing space, and rotatably held in the lubricant reservoir, and transcribes the lubricant in the storing space to the surface of the raceway shaft following the rolling motion. A plurality of recessed parts are formed on the outer surface of the rotating body. The lubricant reservoir includes a pressure imparting mechanism for pressing the lubricant in the storing space toward the rotating body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
