履帯のはずれ止め装置。[Scope of Claim for Utility Model Registration] (1) In a tracked vehicle equipped with a crawler track provided with left and right protrusions guided by a plurality of lower wheels attached to a truck frame, A pin is fixed and installed on the lower surface of the truck frame between the two in parallel with the axis of the lower roller, and a retaining plate with a thickness in the direction orthogonal to the pin is provided in the center of the pin. The pin is attached so that it cannot be moved in the left-right direction but can be rotated around the axis of the pin, and the lower end of the stopper plate is located between the left and right protrusions of the crawler track. Track slippage prevention device. (2) In the crawler track slippage prevention device described in claim 1 of the utility model registration claim, the horizontal projection line of the axis of the drilled pin hole in the slippage prevention plate is set so as not to pass through the center of gravity of the slippage prevention plate. A crawler track slippage prevention device characterized by:
