PROBLEM TO BE SOLVED: To prevent a tongue part from outwardly expanding into the taper shape by outwardly pressed by a second abrasion-resisting knit fabric body, to efficiently apply the lubricant to both side surfaces of a guide part, and to elongate the life of a first abrasion-resisting knit fabric body covering the tongue part without adding the excessive force. SOLUTION: In this device, a bottom edge 46C of a recess 46 of an oil reservoir sheet 36, 36A, 37 and both side edges 46A, 46B are separated, the tongue parts 56, 56A coated with a first abrasion-resisting knit fabric bodies 50, 51 for preventing the unbinding of the side edges are formed on both side edges, the tongue parts 56, 56A are slidably contacted with a guide side surface, further the bottom edge of the recess 46 of the oil reservoir sheet is coated with a second abrasion-resisting knit fabric body 52 for preventing the unbinding of the bottom edge 46C, the second abrasion-resisting knit fabric body 52 is slidably contacted with a top face to the guide part, and a clearance G3 for separating the tongue part and the second abrasion-resisting knit fabric body 52 is formed.
