PURPOSE:To produce high adhesion through prevention of the occurrence of pitch jump, by a method wherein the leg part of a crawler link is movably contained in the recessed groove of a track frame, the crawler link is moved by means of a sprocket, and a power transmission member is situated between the crawler links. CONSTITUTION:A traveling frame assmbly body 1 of a crawler type vehicle is formed with a track frame 2, a crawler link 3, rotated along the outer peripheral surface of a track frame 2, a sprocket 4, rotationally driving the crawler link 3. In this case, a recessed groove 2a, wherein the crawler link 3 is moved, if formed in the whole of the outer peripheral surface of th track frame 2, and a guide groove 2d is formed in a surface 2a positioned facing the recessed groove 2b. Meanwhile, a leg part 3a, engaged internally of the recessed groove 2a, is situated to the crawler link 3, and a rotary shaft 6, rolled in the guide groove 2c, is situated between the leg parts 3a. A power transmission member 13 is projected from the front and the rear end surface of the crawler link 3, and an annular seal member 14 is located in a manner to surround the power transmission member 13.
