の潤滑装置。 A track rail having track grooves formed in the longitudinal direction on both sides of a rod-shaped body having a substantially rectangular cross section; It consists of a casing in which raceway grooves facing the respective raceway grooves are formed in the longitudinal direction and a return path is formed in the longitudinal direction, and side plates attached to the front and rear of the casing and in which a direction change path is formed. , a slide unit in which endless circulation paths in which rolling elements roll are formed on both sides by the raceway grooves, the bidirectional change path, and the return path, and a large number of rolling elements inserted in the endless circulation paths. In the infinite linear motion guide unit that allows the track rail and the slide unit to move relative to each other via rolling elements, a nipple hole is bored in the outer surface of the side plate, the nipple hole is connected to an oil supply path, and the nipple hole is connected to an oil supply path. The supply passage is communicated with an oil passage formed in the horizontal direction via a short communication passage provided on the center line of the side plate, and both ends of the oil passage are provided symmetrically on both sides of the side plate. A lubricating device for an infinite linear motion guide unit, characterized in that the lubricating device is opened to a direction change path.
