<p>PROBLEM TO BE SOLVED: To increase the resistance to a thrust load by providing a seal member between a sleeve bearing being the bearing of a pin and an end collar and by providing a spacer between a bracket and a flange part of the end collar. SOLUTION: A sleeve bearing 5 having flange parts 7 is integrated with a first member 1 of an arm member or the like. An end collar 4, an annular seal material 12 and an annular seal material retaining member 13 are integrated with a bracket 3 of a second member 2 which can swivel. The first and second members 1 and 2 are put in proximity to each other and a pin 6, an O ring 18 and an end plate 10 are fitted in assembly and fastened by a male screw 20. The end collar 4, the seal material 12 and the retaining member 13 are brought close to the flange part 7 in the axial direction of the pin 6 and the seal material 12 are compressed. Moreover, a spacer 17 is inserted in a gap between the flange part of the end collar 4 and the bracket 3. Since a thrust load is transmitted through the flange parts according to this constitution, the value of the thrust load being bearable can be increased.</p> |
