も使用可能になる効果がある。(Effects of the Invention) As described above, the gear lubrication device of the present invention rotates the idler gear through the gear of the gear train mechanism, and moves the lubricating oil sealed in the space of the idler gear outward in the radial direction by centrifugal force. The lubricating oil oozes out to the tooth surface of the idler gear through the open air bubbles in the idler gear made of porous material and adheres to the tooth surface of the gear of the gear train mechanism, thereby preventing evaporation of lubricating oil in a vacuum. It is possible to stably supply lubricating bolt to the meshing part of the guide wheel without causing damage. In addition, the above action continues while the idler gear is rotating, but the amount of lubricating oil supplied from the idler gear to the gears of the tooth train mechanism is small, compared to the case where the solid lubricant is used. In addition to being able to supply lubricating oil for a long period of time, there is almost no scattering of lubricating oil to the surrounding area, and there is no need for a sealing device surrounding each gear and idler gear of the tooth train mechanism, even when exposed to the space (vacuum) environment. It has the effect of making it usable.
