The annular seal bearing member 161 is formed by a steel egg (10), and the _ hole 161 is fixed to the inner side of the outer panel (10). UU0, sleeve Two::: Seal: 162 as shown in Figure 3 to Figure 5 is embedded in the lining. And located in the ring (four) bearing member (6) and the inner plate 110-shaped: bearing::?:::, made of polyurethane rubber, in the face of the torus according to the "sealing ... =: formed with a double-headed seal The seal-like bearing member (6) is pressed against the inner side surface 152 of the outer panel 15〇13 200827268, and the wetting of the joint pin 140 and the bushing 12 is suppressed, and the leakage of the external dust into the joint pin 1 40 and the jacket can be suppressed. ! Between 2 。. As shown in FIGS. 3 to 5, the steel 4 seal ring 164 is placed on the outer side of the annular seal bearing member 1 61 at a predetermined interval so as to be accommodated in the projected area of the inner plate u and the outer plate (scm435). It can suppress the intrusion of foreign matter such as iron ore, coal knives, and sand discs into the inner side surface 152 of the outer panel 15 and the outer surface of the inner panel 110, and prevent the damage of each sealing member. Γ 状文二? 2: Sexual loose seal, 163 as shown in Figure 3 to Figure 5, is clamped in the ring = bearing her cattle 161 ring seal bearing part "η outer surface and steel 饴 饴 ring 1 64 Between the inner circumference and the inside, ', the second, the second elastic (four) ring 163 series, the Nylon resin-made Ο-type ring, can be used in addition to the connection lock 1 4 彳 and the Tuen Mun factory... The outer peripheral surface 143 and the lining # 120 The wet π oil leaks between the inner peripheral faces 121 and suppresses the intrusion of external dust. The seal mechanism plate 110, the joint pin 140, the bushing 120, and the ring shape of the sealed chain of the present embodiment are obtained. The seal bearing member 161, the elastic spring αα α ^ ^ ^ ^ ^ ^, the mountain seal 162, the steel seal ring 164, the brother 2 ... seal ring 163 are composed of a total of eight members. Therefore, the chain is activated due to the stagnation The centrifugal force generated by the dowel 1 4Π I acts on the annular seal bearing member 161 between the sealing joint, the port pin 140 and the bushing 12, the wide, the inner plate 110, the outer plate 15〇, the ring (6), and the second elastic The sealing seal ring 162 and the steel seal are made into a curved shape of a complex shape, and the shape of the oil is leaked out, and the leakage of the lubricating oil can improve the sealing effect. & Oil oil deceleration '14 14 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 27 161, the i-th elastic seal ring, the steel seal ring 164, and the second elastic seal ring 163 are damaged by abrasion between the inner and the inner, and the sealing effect is maintained for a long period of time, and the meandering structure can be further utilized to prevent dust from intruding from the outside. Further, the disk-shaped seal bearing portion 161a of the steel annular seal bearing member 161 is located between the end surface 122 of the bushing 120 and the inner side surface m of the outer plate 15A. Therefore, the inner side surface 152 and the lining of the outer panel 150 can be completely avoided. The end surface 122 of the sleeve 120 is in sliding contact, so that only the surface roughness of the disc-shaped seal bearing portion 161a is small, so that it is not necessary to apply the surface processing to the inner side of the reverse 150, and the inner surface of the outer panel 150 can be suppressed. The sliding contact wear between the side surface 152 and the bushing 12 and the surface 122 is such that the inner connecting portion formed by the meal forming and the inner panel 1 1 〇 and the roller 130 is deflected in the chain width direction. Knowing the inner link in the chain width The direction deviation causes frictional damage which is easy to occur on the side where the gap between the inner panel 11 G and the outer & i 5 变 is narrowed, thereby preventing the service life from being reduced, and also preventing the gap between the inner panel 1 10 and the outer panel 15 from being widened as in the prior art. The sealing performance is reduced due to the incompletely sealed state which is liable to occur on the side. The sealing member 161 is externally fitted and fixed to the coupling pin J 4 and abuts against the inner side surface 152 of the outer panel 150. The relative movement between the poorly-sealed load-bearing member 161 and the outer plate 150 can completely avoid the sliding contact between the annular dense-loaded member 161 and the outer plate 15Q, so that the wear of the annular seal-bearing member i6i can be prevented from being damaged. The sealing effect is deteriorated. Further, the first elastic sealing ring 162 is located between the annular seal bearing and the inner plate 110, and the second elastic sealing ring 163 is lost in the inner circumferential surface of the steel ring 164 and the annular sealing bearing member 61. Density = between the outer peripheral surfaces of the carrier 1 6 1 b. (1) ί bearing So, the first! The elastic sealing ring 162 and the second elastic body are internally bored on the inner side surface of the outer plate 150. The outer side 112 2 seals the lubricating oil, so that the sealing effect can be doubled. Further, the outer steel seal ring 164 is disposed in the annular seal bearing member (6) =: Γ1 = foreign matter such as ore, coal, sand disc, etc., invades the outer panel 15. == Between the outer side faces 112, damage to the annular seal member 161, the second elastic seal ring 、, and the second elastic seal ring 163 can be prevented. ί% 164' The first elastic seal ring 162 has a ring-shaped outer cover 150 pressed, and has a 战 战 161
