PROBLEM TO BE SOLVED: To provide an installation structure of an ancillary part of a motion device, thinning the thickness of a case, and enlarging a storage space of the ancillary part such as a lubricant storage body stored in the case. SOLUTION: The ancillary parts 4 and 5 are stored inside the case 6 composed of a material having rubber elasticity at the room temperature such as rubber or elastomer. A port side part 6b of the case 6 is put on an end part of a moving body 2 of the motion device for relatively moving the moving body 2 to a track member 1. The case 6 is installed in the moving body 2 by using frictional force between the port side part 6b of the elastically deformed case 6 and the end part of the moving body 2. The thickness of the port side part 6b of the case 6 is maximally thinned by manufacturing the port side part 6b of the case 6 from the material having the rubber elasticity, and the space for storing the ancillary part inside the case 6 is maximally largely secured.
