Abstract

PURPOSE:To reduce the ground contacting resistance of a belt at the time of making a turn and improve a turning property by tilting first and second movable frames downward by means of a switchingly driving mechanism and reducing the ground contacting length of a crawler belt. CONSTITUTION:Out of rolling wheels 16 which are longitudinally arranged between a driving sprocket 1a and a stretching wheel body 15, a group of three rolling wheels on the front part side are pivotally supported in parallel by a first movable frame 20 while a group of three rolling wheels on the rear part side are pivotally supported in parallel by a second movable frame 21. The first movable frame 20 is pivotally supported by a fixed frame 19 switching around a lateral axis X1 while the second movable frame 21 is pivotally supported by the fixed frame 19 rotatably around a lateral axis X2. A hydraulic cylinder 24 oscillatingly operates an oscillating member 25 to switchingly drive each of the movable frames 20, 21 so that the middle part side thereof is tilted downward.
