<p>PURPOSE:To provide a pin connecting structure for working mechanism in which a regulating member can be easily mounted in a clearance between two members, and the regulating member according to the clearance can be interposed to prevent the outflow of grease and the penetration of earth and sand through it. CONSTITUTION:A pin hole part 17A corresponding to the outer diameter of a pin 10 is formed in the center part of a ring having a prescribed plate thickness, and the outer circumferential part of a first regulating member 17 halved with the pin hole part 17A as the center is bent at a prescribed angle to form an ear part 17B. The first regulating member having one surface in the ear part 17B direction covered with a seal member such as rubber and a second regulating member 18 having the same structure are opposed to each other in such a manner that the seal members make contact with a housing 11 and a pin receiving part 13, respectively, and interposed in a clearance 15, and an O-ring 21 is fitted to a groove part 20 formed between the outer l circumferential parts of the first and second regulating members 17, 18.</p> |
