Abstract: A motion guide apparatus cooling nozzle is provided which can gas-cool a motion guide apparatus. Cooling nozzles 1a and 1b of the present invention are mounted on a block 4 of the motion guide apparatus to cool at least one of a guide rail 2 and a block 4 that is assembled to the guide rail 2 via a rolling element 6 in such a manner as to be movable relatively. The cooling nozzles 1a and 1b include an inner passage 18 into which gas is introduced, an opening 12a configured to emit a gas flow introduced into the inner passage 18, a deflection surface 22a that is provided adjacently to the opening 12a to bend the gas flow emitted from the opening 12a, and a guiding surface 32a configured to attract gas outside the cooling nozzles 1a and 1b.

Abstract: The linear guide 10 includes a track rail 20, a movable block 30, and rollers 40 arranged between the track rail 20 and the movable block 30 and capable of endlessly circulating. A section of the linear guide 10 including an axis line of the rollers 40 and taken vertically across an unloaded roller rolling path 50 or a direction change path 60, the unloaded roller rolling path 50 or the direction change path 60 includes attitude support portions 55 that support an attitude of the rollers 40 rolling on the unloaded roller rolling path 50 or the direction change path 60, and space portions 54, 54a, and 54b that release a lubricant present inside the unloaded roller rolling path 50 or the direction change path 60. With such configuration, a smooth guide motion of a motion guide device is achieved unaffected by the lubricant in an unloaded circulation path.
