PROBLEM TO BE SOLVED: To improve preventing performance of mis-injection or lubricating oil leakage by enabling certain engagement of an injection nozzle body to a roller or an injection port of the roller even if shaft displacement and tilt exist in the roller or the injection port. SOLUTION: This lubricating device has the injection nozzle body 30 movable to two positions: an injection position engaging with a nipple 6 of a roller 2 to allow injection of lubricating oil; and a separation position moving back and separating from this, and is used for injecting the lubricating oil from the injection nozzle body 30 to the roller 2. The injection nozzle body 30 comprises a nozzle body 33 having a cylindrical body 31 having a passage route of the lubricating oil along the center axis and a tip engaging section 32 disposed at the tip of the cylindrical body 31 and engaging with the nipple 6, a cylindrical outer cylinder 34 loosely engaging with the cylindrical body 31 of the nozzle body 33, a body energizing means 35 for energizing the nozzle body 33 so that the center axis of the body 31 of the nozzle body 33 matches with the center axis of the outer cylinder 34, and an energizing means 38 of a tip engaging part for energizing a flange 37 of the tip engaging part 32 to the nipple 6 side.
