At the pin joint where the sliding part between the bush and the pin is lubricated by supplying grease to the internal grease reservoir, the inside of the boss is placed on the outside end of the bush. Fitted with an oil-tight seal,
Additionally, a grease passage leading to the outer periphery of the boss is opened from the gap between the outer end face of the bush and the inner end face of the seal, and a grease guide hose is connected to the port on the outer periphery of the boss in the grease passage. A greasing device for a pin joint, characterized in that it is configured by connecting. (2) Utility Model Registration The greasing device for a pin joint portion according to claim 1, characterized in that a stop valve is provided on a hose for guiding grease outflow. (3) The bracket and the boss are rotatably connected via a pin, and seal members are fitted to the outer end surfaces of the bushes at both the left and right ends of the boss, and seal members are fitted to the grease reservoir inside the boss. In the pin joint part where the sliding part between the bush and the pin is lubricated by applying grease, a seal is provided on the outer end surface of the bush to oil-tightly seal the inside of the boss from the outside. fitted,
Furthermore, a dust seal is fitted to the outer end surface of the seal, and a grease passage is opened from the gap between the outer end surface of the seal and the inner end surface of the duct seal to the outer periphery of the boss.
