PROBLEM TO BE SOLVED: To provide a pallet guide adequate to put a pallet in or out of a spacecraft structure in an aerospace. SOLUTION: A pair of right and left guide rails 20 are provided in the structure. The guide rails 20 are each formed in a sectionally U-shape with a side guide wall 21 and upper and lower guide walls 22, 23, and they are arranged in the structure in the state of mutually facing opening faces. On the right and left sides of the pallet 2, guide mechanisms 30 are mounted each having a wheel 40 rolling-contactable with the upper and lower guide walls and the side guide wall of the guide rail 20 at their insides and supporting shafts 31, 32, 33 for supporting them. The polyimide wheel 40 has a solid lubricating film formed on the contact surface so that it has direct slide contact with the outer peripheries of the aluminum alloy supporting shafts 31, 32, 33 for increasing lubricating performance.
