特徴とするピン結合部構造。 The boss member is rotatably connected to the bracket member via a pin, and the sliding portion between the inner circumferential surface of the bush fitted inside the boss member and the outer circumferential surface of the pin is supplied with grease. In the pin joint portion where the sealing member is fitted over the entire outer periphery of the gap between the facing surfaces of the boss member and the bracket member, a step is provided at both left and right ends of the boss member. A ring-shaped seal member that forms a diameter portion and has a side end surface lip portion on the stepped diameter portion is inserted so as to be able to slide in the axial direction of the boss member, and when the seal member is moved inward, the seal member The lip of the side end surface of the bracket is set so that it does not protrude beyond the end surface of the boss member, and when the bracket member is attached to the boss member, the tip of the lip of the sealing member is brought into contact with the inner end surface of the bracket member, and the seal is sealed with an elastic ring. In addition, an O-ring member is fitted to a cover member provided on the outer side of the bracket member on the pin end side, and the gap between the contact surfaces of the boss member and the bracket member and on the pin end side are fixed. A pin joint structure characterized in that the gap is constructed in an oil-tight state from the outside by the sealing member with a lip portion and the O-ring member.
