PURPOSE: A device for improving the joining structure of end portion connector complements lock function preventing a bolt from loosening by impacts and vibrations occurring on the starting of an endless track vehicle, alleviates stress concentration of associated pins. So the joining structure of the end portion connector improves the maintenance and the intensity reinforcement of the endless track vehicle. CONSTITUTION: An end portion connector assembly connects one shoe body(20A) with the other neighboring shoe body(20B) by using a pair of pins(52A)(52B) as a parameter. The end portion connector assembly comprises an end portion connector(50), a bolt(54), and a rotating prevention device. The end portion connector(50) includes a pair of pin insertion holes(50A)(50B), a dissection hole(50b), a bolt insertion hole(50c), and a screw hole(50d). The pin insertion holes(50a)(50a) are penetrated therethrough to insert the pins(52A)(52A), at both ends. The dissection hole(50b) is open laterally for the pin insertion holes(50A)(50B) to connect with each other. The bolt insertion hole(50c) and the screw hole(50d) are penetrated perpendicular to the dissection hole(50b). The bolts are fitted into the bolt insertion hole(50c) and the screw hole(50d), and the bolt is compulsorily tightened into the pin insertion holes(50A, 50b). The rotation preventing device prevents the pins(52A)(52A) from rotating.
