Claims

[Scope of utility model registration request]

An annular protrusion 3 a that fits between the core protrusions 13 of the rubber crawler 4 is formed on the outer peripheral surface of the idler 3 for tensioning the crawler, and left and right bearings 6 to which the idler 3 is rotatably attached are attached to the left and right side walls of the truck frame 1 . In the rubber crawler type traveling device, the annular protrusion 3 is attached to the track frame 1 so as to be slidable back and forth, and the upper and lower walls 1b of the truck frame 1 are provided with notches 12 into which the idler 3 is inserted.
A plurality of recesses 14 are formed on the peripheral surface of the idler 3.
The idler structure of the rubber crawler type traveling device is formed in a relative arrangement in which the upper and lower walls 1b enter the recess 14 as the notch 12 slides toward the back side.
