WIPO Patent Application WO/2015/025684

Kind Code:

A1

Abstract:

The opening (35a) on one end side of a pin-boss oil passage (35) opens to the inner-circumferential surface of a pin boss part (14) of an upper link (3), while the opening (35b) on the other end side thereof opens to the outer-circumferential surface of the pin boss part (14) of the upper link (3). A lower-link oil passage (36), which serves as a primary-drive-system-component oil passage and is a through-hole passing through a lower-link separation member (10), has an opening (36a) on one end side thereof which opens to a pin-boss-facing surface (33), and an opening (36b) on the other end side thereof which opens to a crank-pin-bearing surface (37). In addition, the other-end-side opening (36b) of the lower-link oil passage (36) is formed in a long and narrow, elongated-hole shape extending in the circumferential direction of the crank-pin bearing surface.
