Abstract

A seat recliner and an oil collecting element can re-collect the lubricating oil between a friction pair to friction surfaces, so as to reduce the wear rate. The oil collecting element is fixedly connected with one component in a friction pair of the seat recliner. The oil collecting element has an end face facing towards the other component in the friction pair, and each of two ends of the end face is provided with a boss, so as to form an oil collecting gap in the middle of the end face. The side face of the boss is an oil guiding face, and is configured gradually closer to the center of the oil collecting gap from outside to inside. During moving, an outer side of the oil guiding face of the boss firstly abuts against an end wall of the other component, so as to block the lubricating oil rolled to the two ends of the other component by the friction pair, and the blocked lubricating oil further flows towards the oil collecting gap in the middle of the end face of the oil collecting component along the oil guiding face of the boss, thus lubricating the friction surfaces. When the friction pair operates at a high speed, the oil collecting gap of the oil collecting element acts as a dynamic oil passage, and collects the lubricating oil to the portion between the friction surfaces continuously.
