PURPOSE:To eliminate the generation of noise and rust by forming a space in an extending and contracting direction in a connecting part of a link prevented from coming into contact with each other and providing rubber between side plates in such a manner as to coat the inside of this space and the periphery of the link. CONSTITUTION:One part of a link 2 is respectively secured to the inside of a side plate 1, and its outside secures a connecting link 3. The link 2 is connected by the two or more links 2. The respective link 2 is prevented from coming into mutual contact with a connecting part and the side plate 1, forming a space S1 in an extending direction and spaces S2 and S3 in a compressing direction. Buffer 4 adhesively mounts both the side plates 1 while coats the link 2, further even a space between the links 2 is filled with the rubber 4 by adhesion. Thus applying the shock absorbing action to act while providing an extending and contracting quality, further the generation of noise and also rust is eliminated. |
