Patent ID: 7637662

Claim:
A rolling guide unit provided with a cylindrical member ( 2 ) through which a rail ( 1 ) passes for the cylindrical member to slide on, raceway paths (a) constituted of a combination of the cylindrical member ( 2 ) and the rail ( 1 ), circuit paths (b) formed in the cylindrical member ( 2 ) and each making interconnection between two ends of each of the raceway paths (a) by way of direction-changing recesses ( 18 ), and a plurality of rolling elements ( 19 ) placed in the circuit paths (b) and the raceway paths (a), the rolling elements ( 19 ) circulating in the circuit paths (b) and the raceway paths (a) in accordance with relative movement between the rail ( 1 ) and the cylindrical member ( 2 ), comprising: mounting holes ( 20 ) formed in the cylindrical member ( 2 ) and having a length in an axial direction of the rail; bar-shaped oiled members ( 21 ) containing an oil respectively installed in the mounting holes ( 20 ); and oil-supply members ( 23 ) each provided with a projecting piece ( 23 c ) having elasticity for making pressured contact with one end of the oiled member ( 21 ); the projecting piece ( 23 c ) having an exposed face exposed along contact faces of the rolling elements ( 19 ) traveling through either the raceway path (a) or the circuit path (b), and in contact with the rolling elements, wherein the oil-supply members ( 23 ) suck up the oil contained in the bar-shaped oiled members ( 21 ) via the projecting piece ( 23 c ) pressured against the one end of the oiled member and supplies this lubricating oil to the surfaces of the rolling elements ( 19 ).
