Title:
LINK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/051391
Kind Code:
A1
Abstract:
In the present invention, an upper link (3) and a lower link (6) are connected via an upper pin (4). The end sections of the upper pin (4) are secured in pin fitting holes (16) of a pair of upper-pin pin boss sections (12). A cylindrical sliding surface (27a) of a bush (27) of the upper link (3) fits rotatably onto a diamond-like carbon (DLC) coating (25) of a center section of the upper pin (. The width (B) of the bush (27) is less than the width (A) of an upper-link-side pin boss section (20). Consequently, the cylindrical sliding surface (27a) does not overlap an unfinished coating region (25b) of an end section of the DLC coating (25), and burn-in in the unfinished coating region (25b) and peeling of the DLC coating (25) are suppressed.
