Abstract
PURPOSE: To enable attaching of an elastic toroidal object under a condition to wind a track chain around, by a method wherein a segment-shaped elastic toroidal object is placed at both sides of a projection part on a periphery of an idler astride the projection part.
CONSTITUTION: When an elastic toroidal object 8 is secured to an idler 2, after tube holes 30A and 30B in each segment of the elastic toroidal object 8 match a bolt hole 32 in the idler 2, a bolt 34 is inserted through the matched hole 32 from the side of the idler to secure the toroidal object 8 thereat. This facilitates the installation work of the elastic toroidal object to the idler. No bolt fixture hole is machined in the outer periphery wall of the idler 2, and prevents the deterioration of the strength of the idler. Additionally, this eliminates the need for the formation of a concavity, wherein a bolt is housed, in the outer periphery surface of the elastic toroidal object 8, which result in preventing the breakage starting from the concavity due to repeat contact with a track bush 14.
