PURPOSE:To improve durability of a pin and a link, by a method wherein two rolling contact pins are used. CONSTITUTION:Two rolling contact pins P are engaged with pin holes 4 and 5. When the D-shaped rolling contact pin P is bent, it has a relief space. A radial load from a block B to the pin P is collected by a contact pin (a). A peripheral load from the block B to the pin P is collected by a contact line (b). A radial load from the block B to the pin P is collected by a contact line (d). A peripheral load from the block B to the pin P is collected by contact lines (c) and (e). The use of two rolling contact pins which are arranged so that the outer peripheral curves are brought into contact with each other causes prevention of production of slide friction between the pin and the link and enables improvement of durability of the pin and the link.
