A guide device includes a track member and a moving member with rolling elements interposed therebetween. A lubricating path is formed in the moving member for supplying lubricant to a circulation path for the rolling elements. The lubricating path has a common path including an inlet portion that serves as a supply port for the lubricant, a first path through which grease flows, and a second path through which lubricating oil flows. A cross-sectional area of the second path is smaller than a cross-sectional area of the first path, and in the common path, a second communication portion of the second path is located closer to the inlet portion than a first communication portion of the first path. Further, the guide device includes a plug member for blocking the inlet portion of the common path, the plug member being removable and able to be moved within the common path.

Motion guidance device

Provided is a screw device nozzle that can gas-cool a screw device effectively. A screw device cooling nozzle () of the present invention is placed in such a manner as to surround at least one of a screw shaft () and a nut (). The cooling nozzle () includes an internal passage () into which gas is introduced, an opening () for releasing the gas flow introduced into the internal passage (), a deflection surface (), provided adjacent to the opening (), for bending the gas flow released from the opening (), and a guide path () for drawing in gas outside the cooling nozzle ().
