Abstract: Provided is a construction machine in which a pair of boss parts (17L, 17R) coupled via a boss pipe (18) are welded to a tip end of an arm (7), a coupling pin (16) is rotatably supported in bushes (20L, 20R) of the respective boss parts (17L, 17R), and brackets (8b) of a bucket (8) are coupled to opposite ends of the coupling pin (16). An inner pipe (25) is fitted onto the coupling pin (16) on an inner circumferential side of the boss pipe (18), and defines a grease passage (26) between the coupling pin (16) and the inner pipe (25). Left and right gaps between the boss pipe (18) and the inner pipe (25) are closed with side plates (27L, 27R), and a pair of grease chambers (28L, 28R) communicating with each other via the grease passage (26) are defined. A grease supply pipe (29, 30) has a base end welded to a center of an outer circumferential surface of the inner pipe (25) in an axis (C) direction, and a tip end opened in a left side plate (7L) of the arm (7), so that a nipple (33) is mounted to the tip end.

Abstract: Between an inner race and an outer race, a plurality of thrust rollers supporting the inner race and the outer race capable of relative rotation are provided. A thrust cage for retaining each thrust roller capable of rolling is composed of a plurality of cage separate bodies separated and arranged in a roller accommodating space. The cage separate body has two projecting portions having a semicircular cross-sectional shape provided on an outer wall surface of an outside connecting portion spaced apart from each other in a peripheral direction of the outer race. With relative rotation between the inner race and the outer race, when each cage separate body is displaced toward an inner peripheral surface side of the outer race, a top portion of each projecting portion is brought into contact with the inner peripheral surface of the outer race.
