Abstract: There is provided contact, sliding, fitting-in and ornamental members having a surface treatment structure in which contact resistance is low, and lubricating property and wear resistance are excellent, and capable of being used suitably for any use of contact, sliding, fitting-in or ornament, and a method for manufacturing the same. The surface treatment structure 1 having a plating layer formed on the surface of a substrate 2 comprises a lubrication plating layer 5 made of a plating layer of a metal matrix containing fine particles 4 having lubricating property, and a noble metal plating layer 7 formed on the lubrication plating layer 5. Preferably, an anti-diffusive plating layer 3 made of a metal plating layer is formed under the lubrication plating layer 5, and a joining layer 6 made of a strike plating layer of noble metal is formed between the lubrication plating layer 5 and the noble metal plating layer 7.

Abstract: A truck transport apparatus comprises a trolley running rail 11, a front trolley 32 and a rear trolley 33 arranged along the rail 11 in a truck running direction, a truck body 35 connected to the front trolley 32 and the rear trolley 33 at a lengthwise intermediate portion of each trolley so as to permit each trolley to pivotally move horizontally, a driven rod 38 having a front end connected to a rear end of the front trolley 32 so as to make the front trolley 32 free to pivotally move horizontally and a rear end connected to a front end of the rear trolley 33 so as to make the rear trolley 33 free to pivotally move horizontally, and a pair of transport rollers 84, 87 for holding the driven rod 38 therebetween from opposite sides thereof to give the rod a propelling force. The driven rod 38 is extended when the truck is about to move into a curved path of movement from a straight path of movement, while the rod 38 is contracted when the truck is about to move into the straight path from the curved path.
