<p>PROBLEM TO BE SOLVED: To prevent leakage of a lubricating material by providing a sealing material between an end collar and sleeve bearing which become a bearing for a pin connecting a first member to a second member and supporting an end plate of a push bar which pushes out the sealing member. SOLUTION: A sleeve bearing 5 having a flange portion 7 is built in a first member 1 such as an arm member. Also, an end collar 4, a ring-shaped, sealing material 12, a ring-shaped seal-holding member 13 and a ring-shaped push plate 14 are built in a bracket 3 of a second member 2 consisting of a rotatable member 2. Then, first and second members 1 and 2 are located close to each other; and a pin 6, an 0-ring 17 and an end plate 10 are assembled together and tightened with a male screw 20. Also, the end collar 4, sealing material 12 and seal holding member 13 are located close to the flange portion 7, the sealing material 12 is compressed, and a push bar 15 of the push plate 14 is supported by the end plate 10. By doing this, the sealing material 12 and the seal holding member 13 are pushed by the push plate 14, so that the sealing state is secured and any leakage of lubricating material can be prevented.</p> |
