Document Type and Number:
Japanese Patent JP3546230
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To feed a part of an injected lubricant to the periphery of the root section of a vertical pin via a slide contact section or directly by forming a lubricant guiding recessed groove opened in the lateral direction at least on one of link lower side faces kept in slide contact with center link upper side faces of a side link with a pusher.
SOLUTION: In an upper side link 2a with a pusher, lubricant recessed grooves 16 opened obliquely downward from the side are formed on the link lower side face 15 kept in slide contact with the upper side face of a center link on both the right and left sides of an integral vertical pin 4. A part of the oil drips projected toward a pusher 5 flow into the lubricant recessed grooves 16 and are fed to a slide contact face between the peripheral face of the vertical pin 4 and the inner peripheral face of the pin hole of the center link via a slide contact section between the lower side face of the side link 2a and the upper side face of the center link or directly.
