PURPOSE:To widen the interval between both end bearings of a running body which runs along a guide and to lubricate both end bearings by one oil applying member by setting the movement range of the bearing part of the mirror running body and that of the oil applying member in partially overlapping relation. CONSTITUTION:The mirror running body 4 which has both end bearings 4a and 4b with the large interval of length Lc, etc., moves along a guide rod 3 by a distance Ls. The oil applying member 6 is provided to the center of this running body 4 and the length Lc is set to, for example, twice as large as the distance Ls, so that the movement range of the member and that of the bearings 4a and 4b overlap each other. Thus, the interval between both end bearings of the running body is widened for a stable running and both bearings are lubricated by one oil coating member. |
